closure of the atrioventricular valves emergence coincides I systolic heart sound. When closed semilunar and atrioventricular valves fiber length is not changed and only the voltage in the cavities of the ventricles, cialis super active generic
resulting in the pressure in them increases sharply becomes higher than in the aorta and pulmonary arteries, the semilunar valves open and atrioventricular remain closed, and blood rushes into the these vessels. The period of the expulsion of blood, its duration - 0.25. It consists of a phase of rapid ejection phase and slow ejection of blood.
