Questions. Blue veins on the legs: why and whether treatment is needed

Nastya asks:

Hello, I took a blood test from a vein a week ago. At first, almost nothing bothered, only a small bruise appeared and it hurt above the take. After 4 days, a runny nose appeared, the temperature was small, my throat hurt, and after 5 days I noticed blue veins on my wrist, palms and fingers. And more wreaths appeared on the foot. The pain became more on the arm where they took it, above the taking, that is top part and the lower one hurts under any load. The veins turned very blue, I also began to notice a pulsation in the veins in my legs. Diarrhea appeared. Tell me why this could be? Could it be symptoms of infection? I'm just worried that the needle was not sterile (tell me, I'm very worried (thanks in advance.

The presence of prominent veins on the limbs is a constitutional feature and does not apply to pathological conditions, if absent vascular diseases. More clearly visible veins may be after severe physical work, with an increase in blood pressure, with fluid retention in the body, etc. In this situation, an examination by a vascular surgeon or angiologist is necessary, who will conduct a personal examination and assess the nature of the changes, after which, if necessary, appoint you adequate treatment.

Diarrhea has nothing to do with this problem, as a rule, it occurs against the background of gastroenteritis, pancreatitis, food intoxication, intestinal infections etc. In this case, it is recommended to visit an infectious disease specialist and take a stool test for intestinal group, for dysbacteriosis. It is most likely unreasonable to worry about a non-sterile needle, since such situations are practically excluded in modern medical institutions.

Nastya comments:

Tell me, then donating blood from a vein could not affect the appearance of veins throughout the body? It's just that every day they become more and more pronounced all over the body, there is heaviness in the legs and the temperature stays around 37.2. The pain does not go away on the arm where the blood was taken. And could it be a blood clot where they took it? Or is it when a blood clot turns blue only in that place? I also have vegetative-vascular dystonia and recent times I was stressed, could it still affect

Donating blood, as a rule, does not affect the appearance of these changes, which can be expressed as a hematoma in the area of the analysis. I recommend that you visit an angiologist or therapist for a personal examination, who, after the examination, will be able to make the correct conclusion. Vegetative-vascular dystonia can also cause diffuse change vascular tone, as a result of which the veins become more visible.

Science knows that in different living organisms on the planet, the blood has a different shade.

However, in humans it is red. Why is the blood red - both children and adults ask this question.

The answer is quite simple: the red color is due to hemoglobin, which contains iron atoms in its structure.

Red blood is made by hemoglobin, which consists of:

From a protein called globin;
The non-protein element heme, which contains the ferrous ion.

It was possible to find out what gives the red color, but its elements turn out to be no less interesting. What elements give it such a color is an equally interesting aspect.

In the blood:

Plasma. The liquid is light yellow in color, with its help the cells in its composition can move. It consists of 90 percent water, and the remaining 10 percent are organic and inorganic components. Plasma also contains vitamins and microelements. Light yellow liquid contains many useful substances.
Formed elements are blood cells. There are three types of cells: leukocytes, platelets and erythrocytes. Each type of cell has certain functions and features.

These are white bodies that protect the human body. They protect him from internal diseases and foreign microorganisms penetrating from the outside.

This is a white item. Its white hue is impossible not to notice during laboratory research, therefore, such cells are determined quite simply.

Leukocytes recognize foreign cells that can cause harm and destroy them.

These are very small colored plates, whose main function- folding.

It is these cells that are responsible for making the blood:

Coagulated, did not flow out of the body;
Curling rather quickly on the surface of the wound.

More than 90 percent of these cells in the blood. It is also red because erythrocytes have such a shade.

They carry oxygen from the lungs to peripheral tissues, are continuously produced in bone marrow. They live for about four months, then are destroyed in the liver and spleen.

It is very important for erythrocytes to bring oxygen to various tissues of the human body.

Few people know that immature erythrocytes are blue, then acquire gray shade and only after that they turn red.

There are a lot of human erythrocytes, which is why oxygen reaches the peripheral tissues so quickly.

It is difficult to say which element is more important. Each of them has important function affecting human health.

Children often ask questions about the components of the human body. Blood is one of the most popular topics for discussion.

Explanations for children should be extremely simple, but at the same time informative. Blood contains many substances that differ in function.

Consists of plasma and special cells:

Plasma is a liquid that contains useful substances. It has a light yellow tint.
The formed elements are erythrocytes, leukocytes and platelets.

The presence of red cells - erythrocytes and explains its color. Erythrocytes are red in nature, and their accumulation leads to the fact that a person’s blood is of exactly this color.

There are about thirty-five billion red cells that move through the human body in the blood vessels.

Why are veins blue

Veins carry maroon blood. They are red, like the color of the blood that flows through them, but not blue at all. The veins only appear blue.

This can be explained by the law of physics about the reflection of light and perception:

When a beam of light hits the body, the skin reflects some of the waves and looks bright. However blue spectrum she misses much worse.
Blood itself absorbs light of all wavelengths. Skin gives for visibility Blue colour and the vein is red.
The human brain compares the color of a blood vessel against a warm skin tone, resulting in blue.

Blood of a different color in different living beings

Not all living organisms have red blood.

The protein that gives this color in humans is hemoglobin contained in hemoglobin. Other living beings have different fat-containing proteins instead of hemoglobin.

The most common shades besides red are:

Blue. Crustaceans, spiders, mollusks, octopuses and squids can boast of this color. And blue blood is of great importance for these creatures, as it is filled important elements. Instead of hemoglobin, it contains hemocyanin, which contains copper.
Violet. This color is found in marine invertebrates and some molluscs. Usually such blood is not only purple, but also slightly pink. Pink colour blood in young invertebrates. AT this case protein is hemerythrin.
Green. Found in annelids and leeches. Protein - chlorocruorin, close to hemoglobin. However, iron in this case is not oxide, but ferrous.

The color of blood differs depending on the protein it contains. Whatever color blood is, it has huge amount nutrients needed by living organisms. Pigment for each organism is important, despite its diversity.

Video - Secrets and mysteries of our blood

For a long time, people have been worried about the question: why are veins blue and blood red? Experts took up this issue, trying to find and substantiate the answer as accurately as possible. One of the first to notice this feature of the veins were surgeons.

Recently, a new theory about this phenomenon has been circulated in the press by David Irvine from Sydney, who works at the University of Technology. In his opinion, the veins appear blue because he perceives them that way. human vision, as well as the characteristics of the blood and the light absorbed by the skin.

How does human vision perceive the color of veins?

And so, why the veins are blue further remains to be seen. As you know, light waves are different, respectively, they have a similar length. The longest are red, and the shortest are purple, in the space between these two types there are other shades. The eyes begin to distinguish them when the waves enter the field of view. Red waves are not very noticeable under the skin, because they are at a distance of 5-10 millimeters, and because of their size they do not stand out much. Another reason was hemoglobin, which is in the blood, it is he who absorbs the red color.

Why are the veins blue on the arms? In order to see the blue color, it is enough to shine an ordinary white light on your hand. With a different light, such as blue, the veins will not be visible, since this light is easily reflected and scattered without getting into the skin. With white, not tanned skin, blue veins are especially visible.

How does the sun affect color change?

Also why the veins are blue is affected by the normal sunlight. This happens because the tissues of the body absorb red rays, while the blue ones, on the contrary, pass through. The light passes through the fabric a couple of times: inward and backward, during which time the fabric absorbs the red color, while the blue remains intact.

The sun's rays move in the following way:

First, they enter the tissue, then they pass through the skin, subcutaneous fat layer, vein walls and enter the venous blood.
The sun contains the colors of the rainbow. Venous blood has colors: blue, red, yellow, based on this, we can conclude that the blood reflects these colors, and absorbs the other four colors.
Reflected three colors move in the reverse order: they pass through the veins, the fat layer and tissue, and only then become visible to the eye.

Opinion of surgeons

The question of why the blue veins did not bypass the specialists, they put forward a new theory. The fact is that the vessels consist of dense, like oilcloth, white matter. Unlike arteries, which are deep under the skin and have dense walls, veins are transparent in color, so you can clearly see what flows through them. dark blood. When applying colors, blood is dark cherry and the veins themselves are white-gray, the result is blue.

Conclusion of German scientists

The most accurate justification for why the veins are blue was given by German experts. In addition to words, they offered facts that prove the appearance of color:

this color is perceived by the brain;
blood absorbs light;
the skin itself reflects this color.

Most noticeable veins are on white skin, because it practically does not absorb light. Color hits the skin different lengths waves, the red hue has the greatest length and therefore it is reflected by other vessels. Vision will perceive the image that is displayed from the tissues. In the case when the vessels are near the surface of the skin, then almost all of the blue color will absorb the blood, and the rest will be presented as red.

In the case when the vessel is very deep, the light will be reflected before it reaches it, and the person will not see it at all. Practice shows that the vessels display more red color, but the brain perceives it as purple and gives out information that it is allegedly blue.

Hello! Allow me to ask you for advice. My mother (age: 56) noticed that over the course of about 5 years, veins began to appear on both legs with a blue or dark purple tint. They are clearly visible in the photographs (see photo 1-7). Some veins on the left leg, just below the knee, look bulging and tortuous (see photo #3). All places were not subjected to injuries and bruises, with the exception of a single area in photo No. 8, indicated by a circle. As a child, she hit hard in that place. Complaints and pain this moment, the veins do not cause her. However, they are worrisome. How dangerous can it be and is it worth taking any measures now? Can conservative treatment bring improvement, for example, with the help of compression stockings?

Good afternoon. What you describe (veins with a blue or dark purple tint) and seen in the photographs are very closely spaced veins with a very small diameter (reticular veins and telangiectasias). They do not pose any threat to the health of your mother, but given the expansion of veins in the area knee joint it is desirable to make veins lower extremities to exclude pathology in other veins. Having done a study, it will be possible to determine the amount of treatment, including the degree of compression of the stockings. Sincerely, vascular doctor Evgeny Alexandrovich Goncharov.

This issue was most fully investigated by German scientists, who identified three main factors that determine visible blue light.

1) Absorption of light by blood

2) Reflection of light from the skin

3) Color perception by our brain (dress, hello!)

The bluest veins appear on light skin (hence the "blue blood"), the color of which is due to the fact that it weakly absorbs light of any wavelength.

Blood, on the contrary, perfectly absorbs light, especially in the short and medium wavelengths, that is, the red color is slightly worse, and therefore we see it as red.

So, the color of all wavelengths falls on the skin. Red light possessing greater length waves, will penetrate the tissues better, plus, it will be reflected by the vessels encountered. Our eye will see the picture that the light reflected from our tissues will give us.

Thus, if the vessel is located close to the surface of the skin, then almost all of the blue light is absorbed by the blood in the vessel, and part of the red is reflected - ...

What you will not find on the net. Even the question of the color of blood and veins is often accompanied by assumptions and fiction, although most people actually know the answer to it. Yes, everything is simple here - the blood is red, only of different shades, depending on the amount of hemoglobin in it and oxygen enrichment. Everything as biology and BJD teaches at school: arterial blood (rich in oxygen, coming from the heart) is bright scarlet in color, and the venous one (which gave oxygen to the organs, returning to the heart) is dark red (burgundy). The veins that are visible from under the skin are also red when blood runs through them inside. After all, on their own blood vessels transparent enough. But still, many people have questions such as “Why is blood different color and what does it depend on? and "Why are veins blue or blue?".

What determines the color of blood?

The red color of blood can have different shades. Oxygen carriers, that is, erythrocytes (red blood cells), have a shade of red in ...

Why are veins blue?

Venous blood (in the photo it is in the right vial *) is dark red (crimson). Veins are blue. How can this be?

There is even an assumption that deoxygenated blood actually blue, and it turns red only when it flows out and comes into contact with air. This, of course, is not true: when blood is taken from your vein in a hospital, the blood does not come into contact with air - but it is still red.

Let's follow the flight of the sun's rays

1) The rays of the sun enter the skin, pass through the skin, through the subcutaneous adipose tissue, through the wall of the vein - and reaches the venous blood.

2) The rays of the Sun contain the seven colors of the rainbow. Venous blood has a purple (red + blue + yellow) color, so it reflects these three colors, and absorbs all other colors.

3) Red, blue and yellow rays reflected by blood move back: they pass through the wall of the vein, subcutaneous fatty tissue, skin - and enter our eye.

The trick here is...

This is explained simply by two things. First, there are red blood cells containing hemoglobin in the blood. It carries oxygen and, in the process of capturing molecules, oxidizes and becomes bright red. Hemoglobin containing oxygen is called oxyhemoglobin. It flows through the arteries, branching into many capillaries, where it is given to the cells of the body. This makes the hemoglobin turn purple-blue, which is why the veins look like that. If you take blood from a vein, then it, in contact with air, instantly becomes red again.

Secondly, the skin absorbs approximately 50 percent of the red wavelengths and returns the rest back, while the blue wavelengths absorb only 30%. That's why the veins look blue.

The veins of the extremities are of particular importance, since the arms and legs require a good supply of oxygen, as they are the most active parts of the body. Distinguish between superficial and deep veins. Deep - these are paired veins that accompany the arteries of the fingers, ...

Blood in the human body circulates in a closed system. The main function of the biological fluid is to provide cells with oxygen and nutrients and output carbon dioxide and products of exchange.

A little about the circulatory system

The human circulatory system has complex device, biological fluid circulates in small and big circle circulation.

The heart, acting as a pump, consists of four sections - two ventricles and two atria (left and right). Vessels that carry blood away from the heart are called arteries, and those that carry blood to the heart are called veins. Arterial is enriched with oxygen, venous - with carbon dioxide.

Thanks to interventricular septum, venous blood, which is located in the right side of the heart, does not mix with arterial blood, which is in the right section. Valves located between the ventricles and atria and between the ventricles and arteries prevent it from flowing in the opposite direction, that is, from the major artery(aorta) to the ventricle, and from the ventricle to ...

If blood is red, why are veins blue?

(Asked by E. Perrins, Eastwood, New South Wales, Australia)

As mentioned above, red blood cells, occupying about 40% of the blood, contain hemoglobin. As red blood cells pass through the lungs, hemoglobin grabs oxygen and binds to it, causing it to turn bright red. The term "oxyhemoglobin" is used to refer to hemoglobin combined with oxygen. Oxyhemoglobin is pumped from the heart through the arteries. Red blood cells containing oxyhemoglobin then enter the capillaries, where they give oxygen to other tissues. After hemoglobin loses oxygen, it turns purple-blue, and then it is called deoxyhemoglobin. On its way back to the heart, deoxyhemoglobin travels through veins, which appear blue through the skin. However, if blood is drawn from a vein, it will react with the oxygen in the air and immediately turn red.

When we say "Blue Bloods" we mean people of royal lineage. Documentally, this term originated in 1834 in Spain. There is a myth that this phrase describes a condition caused by a rare genetic defect that is common among the royal families of Europe, due to their habit of marrying and marrying only members of other European noble families. This interbreeding led to the development of a disease called "hemophilia", which in turn gave rise to the phrase "blue blood".

Queen Victoria was indeed genetically prone to hemophilia. She was nicknamed "The Grandmother of Europe" thanks to a large number children and grandchildren in royal houses throughout Europe. All this contributed to the spread of this gene.

A significant shortcoming of this theory is that hemophilia does not make the blood blue. It simply means that the body lacks certain substances in the blood that help blood clot. Depending on the type of hemophilia, the blood...

Blood is a combination of many substances - plasma and shaped elements. Each element has strictly defined functions and tasks, certain particles also have a pronounced pigment, which determines the blood color. Why is human blood red? The pigment contained in hemoglobin is red, it is part of the erythrocyte. It is for this reason that there are organisms on Earth (scorpions, spiders, monkfish) whose blood color is blue or green. Their hemoglobin is dominated by copper or iron, giving the characteristic color of the blood.

To understand all these elements that fill the blood, it is necessary to understand its composition.

Composition of the blood

Plasma

As already mentioned, one of the components of blood is plasma. It takes up about half of the blood composition. Blood plasma brings blood into a liquid state, has a light yellow color and is somewhat denser than water in its properties. Plasma density is provided by substances dissolved in it: antibodies, ...

Even though each person's appearance is unique, general structure people's bodies differ little from each other. For example, we all have five fingers on our hands (of course, except for the rarest exceptions) or feet. Or look at your veins - what color are they? Probably greenish-blue, like many others. It is a completely different question why they are of this particular shade, because the blood is red, which means that the veins should be the same color. But not everything is so simple.
The fact is that the blood flowing through the veins contains a certain amount of carbon dioxide, which, when mixed with other components, colors it in dark color. Since the skin and walls of the veins add some distortion, they end up looking bluish to us. According to another theory, the whole thing lies in the fatty layer between the dermis and fascia, which absorbs low-frequency light that penetrates the dark vein and reflects the blue wavelength.
You can even conduct an appropriate experiment. This requires...

The blood in them is not red - it is just so bluish, because it has given its oxygen to the body. Red blood is in the ARTERIES. Those. the body has two systems - inflow and outflow of blood, involved in the delivery of oxygen .. So far blood is coming from the lungs - it is scarlet. When he gives up oxygen, the color changes .. but in general, I should have taught biology at school ..% -) (Of course, not so "blue" blood, first of all - it's just dark. :-))

Well, I don't want to check, but as far as I know, if you open the veins, it will pour out a dark red, not blue at all. And here they are wreaths, naturally blue, not purple. So you didn’t convince me personally, I don’t know how the author of the post :)))))))))

But still, many people have questions such as “Why does blood come in different colors and what does it depend on? And “Why are veins blue or blue?

Which vessels carry the darker blood and how does the circulatory system work?

The constant movement of blood in a closed circuit cardiovascular system, which provides gas exchange in tissues and lungs, is called blood circulation. In addition to saturating the organs with oxygen, as well as cleansing them of carbon dioxide, blood circulation is responsible for delivering all the necessary substances to the cells.

Everyone knows that blood is venous and arterial. In this article, you will find out through which vessels darker blood moves, find out what is included in this biological fluid.

This system includes blood vessels that permeate all tissues of the body and the heart. The process of blood circulation begins in the tissues where metabolic processes through capillary walls.
