The question regarding what ensures the continuity of blood flow through the vessels is quite interesting. After all, this is the substance of which every person consists. We just know that this is a fact, but rarely think about how the blood movement inside us occurs. And that would not be out of place to know. So, it is worth telling about the most interesting points regarding this topic.
Definition
I would like to start with a term that has long ago indicated such a process as blood circulation - the movement of blood through vessels. Hemodynamics is the word. And this process arises, as a result of the difference in the so-called hydrostatic pressure in different parts of our circulatory system. How does this happen? In simple terms, the blood begins to move from the area where there is high pressure to the one where it is lower. Everything is logical. This whole process depends on how high the resistance to blood flow is of its viscosity and the walls of all blood vessels. Often the notorious hemodynamics are impaired, and usually this is due to injuries, burns and hypothermia. The norm or abnormality is determined by the volume of blood passing per minute.
More about blood circulation
So, now we should talk in more detail about what ensures the continuity of the movement of blood through the vessels. This substance moves in the body and pulmonary circle. They are better known to us as the large and small circles of blood circulation. But in order to begin to understand their specifics, you need to understand how the main “mechanism” of a person works, his engine. Namely, the heart.
This is the most important organ, which ensures the movement of blood through the vessels. The continuity of blood movement is determined by constant contractions of the heart. Since it is the body that regulates hemodynamics. The human heart is 4-chamber. Arterial blood is located on the left, and venous in the right. They never interfere in the human heart, since they are separated by partitions. What else is worth knowing? The fact that the arterial blood contains oxygen, and it comes from the heart. Venous, on the contrary, moves towards it. And this blood contains carbon dioxide.
About features
Talking about what ensures the continuity of blood flow through the vessels, it is also necessary to say about the functions of hemodynamics. Through a small circle, it turns out to ensure the normal gas exchange process that occurs in the lungs. Because it receives venous blood supplying carbon dioxide. There it is saturated with oxygen. And, changing direction, returns to the heart. But only being arterial. By imagining this process, we can give an answer to the most important question. And it will be as simple as possible. Breathing - this is what ensures the movement of blood through the vessels. The continuity of the movement of blood is determined by the fact that we constantly breathe. We all know that if you stop breathing, your heartbeat speeds up, and then, if you do not absorb air at all, a fatal outcome occurs . Blood stops flowing to the lungs, as oxygen no longer enters the body. Accordingly, there is no need to supply carbon dioxide. And the heart with blood ceases to fulfill its main function.
Vessels
It is also necessary to talk about them. Continuity and the causes of blood movement is a very multifaceted topic. And vessels are an integral part of it. So, there are shock absorbing, resistive, exchange and capacitive. What are they? The first of these are large arteries. The aorta also belongs to the shock-absorbing vessels. They have special walls, characterized by elasticity - and it is thanks to this quality that continuous hemodynamics is ensured.
Resistive provide high pressure in large vessels, and also regulate the blood circulation in the capillaries, which, by the way, are called exchange. Differ in thin walls. Provide a gas exchange process throughout the vascular system. And it is thanks to the capillaries that all waste substances are removed from the body.
And, of course, capacitive blood vessels. The movement of blood through the vessels is impossible to imagine without them. They got their name due to the fact that it is in them that the overwhelming volume of all the blood that is in a person is located. Namely, 75 percent.
Movement speed
It is also important to know how fast this fluid moves through our vessels, especially when studying the question of what ensures the continuity of the movement of blood through the vessels. So, in the aorta, the speed is about 500 milliliters in one second. In arteries - 0.5 ml at the same time. It’s easy to understand how speed is calculated - scientists have long since derived the total clearance algorithm. However, it is not necessary to talk about this.
Blood in the veins also flows quite quickly - 200 milliliters per second. By the way, here the movement is not due to pressure. It is quite low in the veins. Venous blood moves due to the exerted force on the walls of the vessels of the muscles of the muscles.
Violations
Unfortunately, diseases associated with blood circulation overtake many people. And they are often the cause of early deaths. Stroke, heart attack, hypertension - all these names are well known to us. And they are associated with blood circulation. In vain, many do not pay attention to their health. Indeed, prevention, in fact, is extremely simple and does not require large financial costs. Although some may have a hard time. Since you need to completely stop smoking. It is not surprising why today there are so many people suffering from cardiovascular diseases - you just need to look at the number of smokers.
You should also drink alcohol in moderation. Of course, it’s better to do without it. Physical activity will also not be superfluous. You don’t need to go to the gym every day and spend three hours there for training - just 15-20 minutes a day is enough.
And, of course, you need to monitor your diet. It is not necessary to transmit and get involved in too fatty foods, otherwise cholesterol plaques form on the walls of blood vessels, the lumen of which narrows and, as a result, impaired blood circulation. It is better to replace junk food with fruits, vegetables, citruses, dairy products, and mineral water. This will be good.
