Healthy blood vessels: a life without cardiovascular diseases

Blood in our body serves as a binderan element that ensures the vital activity of every cell, every organ. Its movement in the body is called blood circulation, thanks to which oxygen, hormones and nutrients come to all tissues and organs, and from there, products of disintegration of waste substances are derived from it. In addition, the blood regulates the body, and protects it from harmful microbes. Continuity of blood circulation is provided by the blood vessels and the heart, which make up the circulatory system, all functions of which are strictly coordinated.

Blood vessels, total the length of which in the aggregate is 100 thousand km, permeate the human body like a giant cobweb, allowing each cell to be saturated with oxygen. The movement of blood occurs directly along the arteries, veins and capillaries.

Arteries are thick-walled vessels, through whichthe movement of blood comes from the heart. They are very elastic and, depending on the volume of the blood pumped by the heart, can expand or contract. Arteries carry blood enriched with inhaled oxygen, that is, "clean". The veins, on the contrary, produce an outflow of blood filled with carbon dioxide. On them the blood moves to the heart. Venous walls are less thick than arteries. Capillaries are tiny blood vessels with very thin walls, through which oxygen and nutrients are transferred from the blood to cells and the conversion of carbon dioxide and metabolic products from the cells into the blood.

The largest (in cross section reaching 5cm) a blood vessel in the human body - the aorta that branches into arteries, arteries - to arterioles (smaller vessels), and those in turn to capillaries.

The impetus to the movement of blood is the heartreduction. The movement of blood occurs in two circles: a small (pulmonary) and a large circle of blood circulation, a continuous flow. When moving through a small circle, it is freed from carbon dioxide and saturated with oxygen. In a large circle, on the contrary, it gives oxygen and carries nutrients, taking carbon dioxide and separation products.

Human blood vessels are extremelyan important role in the processes of life. They were called "the main lines of life": they unite literally all the cells of the body, they ensure its well-coordinated work.

Scientists say that the blood vesselswear out and age somewhat earlier than other systems of the body. And the more disdainful a person relates to when and what he eats and drinks, if he is not actively involved in sports, that is, the more disorderly his life, the faster the biological debris and various slags are deposited on the walls of the vessels. Slagging of blood vessels leads to a deterioration of the blood supply to the body, which, in turn, causes a shortage of necessary nutrients in the tissues. So all the known diseases develop to us, and so the aging of the organism takes place.

Cardiovascular diseases along with diabetesand oncological diseases today firmly hold the palm tree among the most dangerous and widespread diseases. The group of diseases of the blood vessels and heart includes the following:

- cardiac ischemia,

- rheumatic heart disease,

- diseases of the blood vessels of the brain,

- Congenital heart defect,

- pulmonary embolism,

- deep vein thrombosis,

- Peripheral arterial disease.

Such acute diseases as strokes andheart attacks occur mainly as a result of blockage of blood vessels, which then prevents the flow of blood to the brain or heart. The reason for blockages is fat deposits on the inner walls of blood vessels that supply blood to the heart or brain.

Particular complexity in the identification of vascular diseases andheart is their asymptomatic course, so timely diagnosis will help not only to avoid serious complications, but in some cases - to save lives.
