Cardiovascularsystem away from the heart to all parts of the body is carried by the blood of oxygen and nutrient delivery to all cells in the body play a vital role. without any obstruction to smooth flow of blood and organ tissue distribution of food, blood, development of an injured vessel is extremely important for the clotting process, but natural and necessary part of healing. Normally, as a result of illness or injury, bleeding is stopped by clot formation, blood coagulation results in about five minutes. blood clotting-that the body's cardiovascular system in the All-Merciful Lord-is made by, however, a solid mass of blood nonstop conversion as embedded, then the impossible life would be in the internal formation of blood clots vital organ blood flow obstacles. Out a normal blood vessels in the cardiovascular system, blood circulation is expected to be eroded as a result. However, blood in blood in the rapid transition of friction along the inner surface of blood vessels, as we smooth the flow of blood to regulate the cardiovascular system, with excellent results is not established. All vascular endothelial cells in the inner surface forming a thin layer play a significant role in preventing any damage which is created in this manner. Previously, a protective layer of endothelial cells were thought to be simple, now they have become much research interest. Blood vessels consist of two basic cells: smooth muscle cells and endothelial cells. Strength and tone of vascular muscle cells is responsible. Today, the role of the endothelial layer I know beyond a simple physical barrier. Moreover, the role of 25 different items of blood coagulation, cell proliferation, regulation of vascular permeability and the functioning of the immune system, the game will be released by endothelial cells. Endothelial cells, 10-15 microns and 20-25 microns wide and long. They have a single layer of cells in the inner vessel wall endothelial bulunur.bir adults around the body, the total is 5000-6000m2 and around 2.5 kg in weight. capillary endothelial cells during inflammation in the endothelial structure, one of them under a microscope, can be seen but their total length is approximately 96 000 km. Of the arteries that bring blood to the capillaries and can be transmitted through. In this phase, gas, liquid and feeder vessels and cells and tissues of oxygen and nutrients are supplied through the out. By contrast, their currents and other waste liquids, and for capillaries through both capillary taking place outside these material changes, endothelial cell layer permeability and capillary system pressure to compensate you for prepared. released during inflammation in heart failure and fluid pressure imbalance due to an increased amount of fluid intake is not sufficient to compensate for lost. swelling in the area in question, edema, rash, fever-like symptoms that arise in response to inflammation and pain is necessary to underline, a process that is not harmful. In contrast, our body's defense mechanism is a miracle; inflammation protects the body against serious injury. For example, inflammation, the body forms around a bee sting to prevent the spread of venom. Endothelial cells also has an important role in inflammation. Chemical molecules are secreted by endothelial cells in inflamed points by expanding the reaction vessel and thus cause increased perfusion. Then, the endothelial layer is ready to settle for leukocytes, which causes inflammation in the first place is a neutralizing substance.
