Which blood is saturated with carbon dioxide. Conversion of arterial blood into venous blood. Circulatory system. Circulation circles. How to stop arterial bleeding
The blood that constantly circulates in the body is not the same everywhere. In some areas vascular system it is venous, on others it is arterial. What is this substance in each case, and how is it different? deoxygenated blood from arterial? This is discussed below.
General information
Among the functions of blood, the most important is supplying nutrition and oxygen to the tissues, as well as freeing the body from metabolic products. All this movement of vital fluid occurs along a closed trajectory. In this case, there is a division of the system into two sectors, called circulatory circles. Small - passes through the lungs, where oxygen enters the blood. Large - permeates the entire body, its organs and tissues.
The beats of the heart make the blood move. The most large vessels come directly from this body. Gradually they narrow, branch and turn into capillaries. Below are arteries, veins and more small vessels and the movement of blood is shown:
Comparison
Each type of blood has its own composition. Arterial- This is the one that is saturated with oxygen. In addition, it contains a sufficient amount useful elements because it nourishes the cells of the body. In a large circle, such blood flows, respectively, through the arteries, in the direction from the heart. But in small things, despite the name, through the veins.
Everything happens the other way around in the case of venous blood. In the large circle it moves to the main organ through the veins, and in the small circle it moves from the heart to the lungs through the arteries. Such blood carries a lot of carbon dioxide and metabolic products, but there are practically no nutrients in it. Arterial blood turns into a liquid with the specified composition after recoil useful components body tissues. Thus, an important substance, circulating along a closed path, regularly changes its type when passing through certain sections.
Let us name other signs that make up the difference between venous blood and arterial blood. The visual differentiating factor is color. U venous blood it is deep, dark red with a cherry tint. Arterial fluid, in turn, is brighter. It was revealed that her temperature was slightly lower.
Another feature by which comparison can be made is the speed of movement of the train of both types. Thus, venous blood has a more measured flow. This is explained both by the action of certain physical forces and by the fact that the veins are equipped with valves that control such movement. By the way, these vessels are clearly visible under the skin in certain areas of the body, for example in the wrist area.
Because of low pressure venous blood, which is also thicker, comes out calmly when the body is damaged. It's easier to stop her. Meanwhile, arterial bleeding, which has an intense pulsating nature, is very difficult to cope with. This phenomenon is very dangerous for human life.
What is the difference between venous and arterial blood? The fact is that when determining diseases, the first type of material is more often collected. After all, it is venous blood rich in products vital activity, can tell more about any problems in the body.
Arterial blood- This is blood saturated with oxygen.
Deoxygenated blood- rich carbon dioxide.
Arteries- These are vessels that carry blood from the heart.
Vienna- These are vessels that carry blood to the heart.
(In the pulmonary circulation, venous blood flows through the arteries, and arterial blood flows through the veins.)
In humans, in all other mammals, as well as in birds four-chambered heart, consists of two atria and two ventricles (in the left half of the heart there is arterial blood, in the right - venous, mixing does not occur due to a complete septum in the ventricle).
Between the ventricles and atria are flap valves, and between the arteries and ventricles - semilunar. The valves prevent blood from flowing backwards (from the ventricle to the atrium, from the aorta to the ventricle).
The thickest wall is at the left ventricle, because it pushes blood through the systemic circulation. When the left ventricle contracts, it creates pulse wave, as well as maximum blood pressure.
Blood pressure: in the arteries the largest, in the capillaries the average, in the veins the smallest. Blood speed: in the arteries the largest, in the capillaries the smallest, in the veins the average.
Big circle blood circulation: from the left ventricle, arterial blood flows through the arteries to all organs of the body. In capillaries great circle Gas exchange occurs: oxygen passes from the blood to the tissues, and carbon dioxide passes from the tissues to the blood. The blood becomes venous and enters through the vena cava right atrium, and from there - into the right ventricle.
Small circle: From the right ventricle, venous blood flows through the pulmonary arteries to the lungs. Gas exchange occurs in the capillaries of the lungs: carbon dioxide passes from the blood into the air, and oxygen from the air into the blood, the blood becomes arterial and enters the pulmonary veins through the pulmonary veins. left atrium, and from there - into the left ventricle.

Constant movement of blood through a closed circuit cardiovascular system, which ensures gas exchange in tissues and lungs, is called blood circulation. In addition to saturating organs with oxygen, as well as cleansing them of carbon dioxide, blood circulation is responsible for delivering all necessary substances to the cells.
Everyone knows that blood can be venous and arterial. In this article you will learn through which vessels more dark blood, find out what is included in this biological fluid.
This system includes blood vessels that penetrate all tissues of the body and the heart. The process of blood circulation begins in the tissues where metabolic processes through the capillary walls.
The blood, which has given up all the useful substances, flows first to the right half of the heart, and then into the pulmonary circulation. There she got rich useful substances, moves to the left, and then spreads in a large circle.
The heart is the main organ in this system. It is endowed with four chambers - two atria and two ventricles. The atria are divided interatrial septum, and the ventricles - interventricular. The weight of a human “motor” is from 250-330 grams.
The color of the blood in the veins and the color of the blood moving through the arteries are slightly different. You will learn a little later about which vessels the darker blood moves through and why it differs in shade.
An artery is a vessel that carries biological fluid saturated with useful substances from the “motor” to the organs. The answer to a fairly frequently asked question: “What vessels carry venous blood?” simple Venous blood is transported exclusively by the pulmonary artery.
The arterial wall consists of several layers, these include:
- outer connective tissue membrane;
- medium (consisting of smooth muscles and elastic hairs);
- internal (consisting of connective tissue and endothelium).
Arteries divide into small vessels called arterioles. As for capillaries, they are the smallest vessels.
The vessel that carries carbon dioxide-enriched blood from tissues to the heart is called a vein. Exception in in this case pulmonary vein - since it carries arterial blood.
Dr. W. Harvey first wrote about blood circulation back in 1628. The circulation of biological fluid occurs through the pulmonary and systemic circulation.
The movement of biological fluid in the systemic circle begins from the left ventricle, thanks to high blood pressure, the blood spreads throughout the body, nourishes all organs with beneficial substances and takes away harmful ones. Next, the transformation of arterial blood into venous blood is noted. The last stage is the return of blood to the right atrium.
As for the small circle, it begins from the right ventricle. First, the blood gives off carbon dioxide, receives oxygen, and then moves to the left atrium. Next, through the right ventricle, the flow of biological fluid into the systemic circle is noted.
The question of which vessels carry darker blood is quite common. Blood is red in color; it differs only in shades due to the amount of hemoglobin and oxygen enrichment.
Surely many remember from biology lessons that arterial blood has a scarlet tint, and venous blood has a dark red or burgundy tint. Veins located nearby skin, also appear red when blood circulates through them.
In addition, venous blood differs not only in color, but also in function. Now, knowing through which vessels darker blood moves, you know that its color is due to its enrichment in carbon dioxide. The blood in the veins has a burgundy tint.
It contains little oxygen, but at the same time it is rich in metabolic products. It is more viscous. This is due to an increase in the diameter of the red blood cells due to the influx of carbon dioxide. In addition, the temperature of the venous blood is higher, and the pH is lower.
It circulates through the veins very slowly (due to the presence of valves in the veins that slow down the speed of its movement). Wen in human body compared to arteries, much larger.
What color is the blood in the veins and what functions does it perform?
Do you know what color the blood in the veins is? The shade of biological fluid determines the presence of hemoglobin in red blood cells (erythrocytes). The blood circulating through the arteries, as already mentioned, is scarlet.
This is due to the high concentration of hemoglobin (in humans) and hemocyanin (in arthropods and mollusks), enriched with various nutrients.
Venous blood has a dark red tint. This is due to oxidized and reduced hemoglobin.
At the very least, it is unreasonable to believe the theory according to which the biological fluid circulating through the vessels bluish color, and in case of injury and contact with air due to chemical reaction immediately blushes. It is a myth.
Veins can only appear bluish, this is due to the simple laws of physics. When light hits the body, the skin reflects some of all the waves and therefore looks light or dark (this depends on the concentration of the coloring pigment).
You know what color venous blood is, now let's talk about the composition. You can distinguish arterial blood from venous blood using laboratory research. Oxygen tension - 38-40 mmHg. (in venous), and in arterial blood - 90. The content of carbon dioxide in venous blood is 60 millimeters of mercury, and in arterial blood - about 30. The pH level in venous blood is 7.35, and in arterial blood - 7.4.
The outflow of blood, carrying away carbon dioxide and products formed during metabolism, is carried out through the veins. It is enriched with useful substances that are absorbed into the walls of the gastrointestinal tract and produced by vital substances.
Now you know what color the blood is in the veins, you are familiar with its composition and functions.
Blood flowing through the veins overcomes “difficulties” during movement, which include pressure and gravity. That is why, in case of damage, biological fluid flows in a slow stream. But if the arteries are injured, blood spurts out like a fountain.
The speed at which venous blood moves is much less than the speed at which arterial blood moves. The heart pushes blood out high pressure. After it passes through the capillaries and becomes venous, a decrease in pressure to ten millimeters of mercury is noted.
Why is venous blood darker than arterial blood, and how to determine the type of bleeding
You already know why venous blood is darker than arterial blood. Arterial blood is lighter and this is due to the presence of oxyhemoglobin in it. As for the venous, it is dark (due to the content of both oxidized and reduced hemoglobin).
You've probably noticed that blood is taken from a vein for testing, and you've probably wondered, “why from a vein?” This is due to the following. The composition of venous blood includes substances that are formed during metabolism. In pathologies, it is enriched with substances that ideally should not be in the body. Thanks to their presence, it is possible to identify the pathological process.
Now you know not only why the blood in the veins is darker than the arterial blood, but also why blood is taken from the vein.
Anyone can determine the type of bleeding; there is nothing difficult about it. The main thing is to know the characteristics of biological fluid. Venous blood has a darker shade (why venous blood is darker than arterial blood is indicated above), and it is also much thicker. When cut, it flows out in a slow stream or drops. But as for the arterial one, it is liquid and bright. When wounded, it sprays like a fountain.
Stop venous bleeding It’s simpler, sometimes it stops on its own. Typically, a tight bandage is used to stop bleeding (placed below the wound).
As for arterial bleeding, everything is much more complicated. It is dangerous because it does not stop on its own. In addition, blood loss can be so large that death can occur literally within an hour.
Capillary bleeding can open even with minimal injury. The blood flows out calmly, in a small stream. Such damage is treated with brilliant green. Next, a bandage is applied to them, which helps stop bleeding and prevent pathogenic microorganisms into the wound.
As for the venous, when damaged, blood flows out somewhat faster. In order to stop bleeding, a tight bandage is applied, as already mentioned, below the wound, that is, further from the heart. Next, the wound is treated with 3% peroxide or vodka and bandaged.
As for the arterial one, it is the most dangerous. If you have already been injured and you see bleeding from the artery, you must immediately raise the limb as high as possible. Next, you need to bend it and pinch the wounded artery with your finger.
Then a rubber tourniquet (rope or bandage will do) is applied above the wound site, after which it is tightened tightly. The tourniquet must be removed no later than two hours after application. While the bandage is being applied, a note is attached indicating the time of application of the tourniquet.
Bleeding is dangerous and fraught great loss blood and even fatal. That is why in case of injury it is necessary to call ambulance or take the patient to the hospital yourself.
Now you know why the blood in the veins is darker than the blood in the arteries. Blood circulation is a closed system, which is why the blood in it is either arterial or venous.
In medicine, blood is usually divided into arterial and venous. It would be logical to think that the first flows in the arteries, and the second in the veins, but this is not entirely true. The fact is that in the systemic circulation, arterial blood (a.k.) actually flows through the arteries, and venous blood (v.k.) through the veins, but in the small circle the opposite happens: c. It enters from the heart into the lungs through the pulmonary arteries, releases carbon dioxide to the outside, is enriched with oxygen, becomes arterial, and returns from the lungs through the pulmonary veins.
How does venous blood differ from arterial blood? A.K. is saturated with O 2 and nutrients; it flows from the heart to organs and tissues. V. k. - “spent”, it gives O 2 and nutrition to the cells, takes CO 2 and metabolic products from them and returns from the periphery back to the heart.
Human venous blood differs from arterial blood in color, composition and functions.
By color
A.K. has a bright red or scarlet tint. This color is given to it by hemoglobin, which added O 2 and became oxyhemoglobin. V.K. contains CO 2, so its color is dark red, with a bluish tint.
By composition
In addition to gases, oxygen and carbon dioxide, the blood also contains other elements. In a. k. a lot of nutrients, and c. to. - mainly metabolic products, which are then processed by the liver and kidneys and excreted from the body. The pH level also differs: in a. k. it is higher (7.4) than that of v. k. (7.35).
By movement
Blood circulation in the arterial and venous systems is significantly different. A. k. moves from the heart to the periphery, and v. k. - in the opposite direction. When the heart contracts, blood is ejected from it under a pressure of approximately 120 mmHg. pillar As it passes through the capillary system, its pressure decreases significantly and is approximately 10 mmHg. pillar Thus, a. k. moves under pressure at high speed, and c. It flows slowly under low pressure, overcoming the force of gravity, and its reverse flow is prevented by valves.
How the transformation of venous blood into arterial blood and vice versa occurs can be understood if we consider the movement in the pulmonary and systemic circulation.
Blood saturated with CO 2 enters the lungs through the pulmonary artery, from where CO 2 is excreted. Then saturation with O 2 occurs, and the blood already enriched with it enters the heart through the pulmonary veins. This is how movement occurs in the pulmonary circulation. After this, the blood makes a large circle: a. It carries oxygen and nutrition through the arteries to the cells of the body. Giving O 2 and nutrients, it is saturated with carbon dioxide and metabolic products, becomes venous and returns through the veins to the heart. This completes the large circle of blood circulation.
By functions performed
Main function a. k. – transfer of nutrition and oxygen to cells through the arteries of the systemic circulation and the veins of the small circulation. Passing through all organs, it gives off O 2, gradually takes up carbon dioxide and turns into venous.
The veins carry out the outflow of blood, which has taken away cell waste products and CO 2 . In addition, it contains nutrients that are absorbed digestive organs, and produced by glands internal secretion hormones.
By bleeding
Due to the characteristics of movement, bleeding will also differ. With arterial bleeding, the blood flows in full swing; such bleeding is dangerous and requires prompt first aid and medical attention. With venous flow, it calmly flows out in a stream and can stop on its own.
Other differences
- A.K. is located on the left side of the heart, in. k. – in the right, blood mixing does not occur.
- Venous blood, unlike arterial blood, is warmer.
- V. k. flows closer to the surface of the skin.
- A.K. in some places comes close to the surface and here the pulse can be measured.
- The veins through which the v. flows. to., much more than arteries, and their walls are thinner.
- Movement a.k. is ensured by a sharp release during contraction of the heart, outflow into the. the valve system helps.
- The use of veins and arteries in medicine is also different - they inject medications, it is from this that biological fluid is taken for analysis.
Instead of a conclusion
Main differences a. k. and v. consist in the fact that the first is bright red, the second is burgundy, the first is saturated with oxygen, the second is saturated with carbon dioxide, the first moves from the heart to the organs, the second - from the organs to the heart.
