| Abstrakt: | The heart is the pivot of the blood circulation, the engine that allows to carry the oxygen received from the lungs to the cells of tissues and organs and to exchange carbon dioxide, which represents a waste of the metabolic activity of the cells, at the level of the lungs. The oxygenated blood travels in the organism to organs and tissues through the aorta. This artery brings nourishment to the whole body by dividing into various branches and capillaries smaller and smaller. Blood with carbon dioxide waste returns to the heart through the veins. The aortic valve is one of the four heart valves. It is also called aortic semilunar due to its semilunar shape and is between the left ventricle and the aorta with the function of ensuring that oxygen-rich blood does not go back in its path. The aortic valve is a valve made up of three membranes (cusps) made up mainly of collagen; the valve is placed on a muscle ring and connected through it to the heart wall.
