diastol

Arteries are muscular blood vessel that carries blood from the heart. This function contrary vein function which carries blood toward the heart. The circulatory system is extremely important in sustaining life. Its main function is to deliver oxygen and nutrients to all cells, as well as transporting waste substances such as carbon dioxide. In developing countries, two main death incident caused by infarction of myocardium and artery stroke on the system, such as atherosclerosis. The system has a pressure vessels high on the circulatory system. Blood pressure usually indicates the pressure in the main artery. Pressure at a time when the heart expands and blood enters the heart is called diastol. Sistol pressure means blood pressure when the heart is contracting and blood out of the heart. This can be in the blood pressure measurement with tensimeter or sfigmomanometer. Types of vessels There are several types of vessels on the body: Artery pulmonaris These vessels carry blood that have recently streamed deoxygenation of the lungs. Systemic arteries Systemic arteries carrying blood to the arterioles, and then to the capillaries, where nutrients and gases are exchanged. The Aorta The aorta is the largest artery in the body out of the ventricles of the heart and brings a lot of oxygen. The Arterioles The arterioles is the smallest vessels associated with capillary vessels. Capillaries These vessels are not real vessels. This is where the exchange of substances that become the main function of the circulatory system. Capillaries are the vessels that connect the branches of the artery and the vein branches the least with the cells of the body. Artery and vein that branches, branches and the size of the vessels that the farther from the heart is getting smaller. Capillaries are very smooth and thin-walled.
