Circulatory system

Blood circulation (cardiovascular system) is the distribution of nutrients and blood gases in all body tissues. It also serves as drainage products of metabolism. This process is controlled through the rhythmic contractions of the heart. In humans, then we are talking about closed circulation, which means that only the blood circulates in the vessels and are not empty into body cavities. We divide it into circulation a big heart and a small cardiac circulation.

Large cardiac circulation (body) extends between the body and heart. Blood when it travels through the arteries of the left ventricle into the capillaries, after oxygenation returns through the veins back to the heart, which continues from the right ventricle into the small cardiac circulation.

Small heart circulation (pulmonary) is an exchange of blood gases between the lungs and the heart. Deoxygenated blood moves through the arteries to the lungs and oxygenation after the vein moves from the lungs to the heart.

Proper function of blood circulation ensures vasculature. The largest blood vessels are arteries. They then branch out into arterioles and capillaries. Now capillaries (also called capillaries) are a place where there is a transfer of substances, blood gases and products of metabolism. These blood vessels are further divided into veins and the veins of which are most superior vena cava and inferior vena cava.

Circulatory system diseases in our population belongs to the most used. The culprit is mostly fast way of life and its associated overly stress, unhealthy diet, lack of exercise and indulgence in alcohol and cigarettes. Patients are constantly diagnosed with atherosclerosis, which may be the basis for later myocardial infarction. The solution in the treatment of disorders of the circulatory system, such as bypass surgery, wherein the patient by surgical artificially created vascular clutch.

Such a procedure may not happen if we had timely blood circulation to his attention, and we will not neglect prevention. In it is the basis for limiting animal fat, regular exercise and relaxation, avoiding smoking and alcohol. The diet should be rich in vitamins A, C and E, which are due to its antioxidant effects important in the fight against diseases of the circulatory system.
