The importance of the circulatory system in the human body

The circulatory system of each person plays a very significant role in the life-support of the body with all substances and vitamins that are necessary for normal work and the correct development of the person as a whole. Blood constantly circulates through the venous-arterial system, where the role of the main pump is performed by the heart, which is constantly in constant movement throughout the life of a person. The heart itself consists of the right and left halves, each of which in turn is divided into two internal chambers - a fleshy ventricle and a thin-walled atrium. A healthy heart, which works in the right rhythm, ensures the flow of oxygen not only to all internal organs, but also to all cells, taking simultaneously carbonic acid and other waste products. Thus, the importance of the circulatory system is extremely large.

It is noteworthy that the entire cardiovascular system is in constant development, due to which in physical education and sports with proper selection of exercises it is possible to maintain the body in a healthy state throughout almost the whole of life. Unfortunately, many people do not always understand what the value of the circulatory system is in a person's life and how the lifestyle affects the heart. Proof of this is the sad statistics of the increase in the number of diseases associated with the cardiovascular system. This is hypertension, hypotension, heart attack and so on. That is why all people from the school's bench must realize that the importance of the circulatory system in a person's life is very important, and one must take care of one's own health. The fact is that the blood gives the cells the necessary nutrients, as well as oxygen, which is vital for their growth and development.

Today, in many developed countries, interest in healthy lifestyles increases every year, and the number of people who throw such harmful habits like smoking and drinking steadily increases. In our country, statistics, unfortunately, is not yet so favorable, but already today there is a part of youth who prefers to lead an active lifestyle, engage in tourism and sports. After all, many people just do not know how destructively ethyl alcohol acts on the heart and blood vessels, and who touches the blood, then as a result of poisoning in the blood cells there is a glueing of red blood cells, which can lead to blood clots and internal hemorrhage. Thus, the huge value of the circulatory system of the body is proved by life itself, as much depends on healthy blood. By the way, the composition of blood is also affected by proper nutrition, so if it is balanced and contains a large number of useful and nutritious elements, the slag in the body will be much less. A balanced approach to eating leads to better absorption of nutrients, and also prevents the ingestion of oxidative products into the bloodstream, which adversely affect blood composition. By the way, it will also be useful to learn that fasting helps to cleanse the internal organs of slags, since "hungry" blood cleanses the body, drawing out of it all harmful elements and substances

Everyone wants to have good health, to be able to run and jump, be beautiful and strong. All this wealth is in our hands since youth, and only in time, due to negligence towards ourselves, we gradually lose it. If people understood the role of the circulatory system in the body from an early age, the health of the whole people would become much stronger. Such sports exercises as running in the morning, swimming and hardening with cold water act on the cardiovascular system as well as possible, increasing the adaptive capacity of the body, as well as its resistance to various diseases. Healthy blood ensures the normal functioning of all human organs without exception, helping them to overcome extreme loads in certain vital moments.

Thus, summing up all of the above, it should be understood that the importance of the circulatory system in any organism is enormous, and the heart is the main organ that ensures the possibility of the existence of life as an integral biological system.
