The full circle of blood circulation - an average of 27 seconds. In the human blood vessel system, arterial and venous vessels are distinguished. The largest arterial is the aorta. It passes into large arteries, which are subdivided into arteries smaller, then "flow" into even more miniature arterioles and end with the smallest - capillaries. Their diameter is only 5-10 micrometers. Small vessels are entrusted with a huge mission - they feed the tissues with oxygen and are responsible for the metabolism. Capillaries in the human body so much that if you collect them together and build them in length - about 2.5 times turn around the equator! How to strengthen blood vessels in the human body, this will be discussed in the article.
The venous system begins with the smallest venous capillaries (they take the products of the cellular metabolism from the cells, passing into the vets and then into larger vessels through which the blood returns to the heart to begin a new cycle). A special role in the human body is assigned to the lymphatic system. The lymph bathes all cells and tissues of the body, performs drainage and purification functions (neutralization, ingested bacteria, viruses, foreign particles). When there is no breakdown in our main "water pipe", all the cells get the right amount of oxygen, the blood is perfectly cleaned and comes to the heart in time. This is a pledge of excellent appearance (in fact, the whole body receives the nutrients, including the skin!) And the preservation of health. Alas, there are failures in the vessels.
Atherosclerosis
This formation on the walls of the vessels of the plaques. They partially or completely cover their lumen and lead to oxygen starvation of tissues. Plaques in the arteries can cause a heart attack or stroke - depending on where the clogged vessel is located. From atherosclerosis in the first place will save a balanced diet. After all, plaques in the arteries are delayed because of excess cholesterol. It is worth inviting more vegetables, fruits, leaf greens, oily fish to dinner. They are rich in polyunsaturated fatty acids, very necessary vessels. Meat should be eaten moderately, preferably older beef, lean pork, white chicken meat. The opinion that people after 45-50 years should abandon meat delicacies - wrong. Some citizens normally tolerate steaks and chops - the amount of cholesterol they do not increase. But it is advisable to discuss your menu with a nutritionist. And to control the level of cholesterol - for this purpose a special blood test is done. By the way, there are rumors that the blood vessels can be cleaned. Cardiologists refute this myth. The plumber of our blood supply system, alas, can not be called. From the ailments, the vessels will be relieved by surgery or medications - as the doctor will appoint!
Thrombosis
Due to the contraction of muscles and venous valves, the movement of blood through the veins is always directed upwards. If the venous valves fail to work, chronic venous insufficiency appears, which can be complicated by the formation of thrombi. Particularly insidious are flotation (dangling blood clots). They are not attached firmly to the walls of the vessels. They can come off and move closer to the heart. The main signs of the disease: heaviness and pain in the legs, a sensation of puffiness, tingling, pain along the vein, burning, night cramps, itching, the appearance of a venous network. Vein disease is often called a professional disease of hairdressers, sellers and ... office staff - those who spend a lot of time or sit. Under any circumstances, the legs should be in motion. Gymnastics, cycling, dancing, swimming are good sports for vascular health. It is necessary to avoid sources of heat, which causes the expansion of veins (give preference to low temperatures). It is necessary to normalize the intestines and normalize the weight. Also, do not wear a testicle, squeezing clothes and get the right shoes: give up flat soles and heels above 5 cm.
Puffiness
When microcirculation is disturbed in the lymphatic vessels, edema appears, its extreme manifestation is "elephantiasis" (swelling of the legs).
Harmful
- Smoking - causes spasms of blood vessels.
- Alcohol. Although small doses of alcohol and expand the arteries, lower the level of cholesterol, cardiologists do not advise resorting to such prophylaxis. There is a risk of addiction and dependence.
- Stresses - make the vessels brittle and brittle.
Usefull
- Movement - an hour's walk three times a week hardens the vessels.
- Calmness - learn to philosophically treat unforeseen situations.
- Leaf greens and sea fish - they contain many polyunsaturated fatty acids, which strengthen and increase the elasticity of the vessels.
