WebSystole (left) typically refers to ventricular systole, during which the ventricles are pumping (or ejecting) blood out of the heart through the aorta and the pulmonary veins. The closure of the aortic valve causes a rapid … WebVentricular systole induces self-contraction such that pressure in both left and right ventricles rises to a level above that in the two atrial chambers, thereby closing the tricuspid and mitral valves—which are prevented from inverting by the chordae tendineae and the papillary muscles.

WebApr 10, 2024 · Diastole and systole are two phases of the cardiac cycle. They occur as the heart beats, pumping blood through a system of blood vessels that carry blood to every part of the body. Systole... WebOct 21, 2024 · A ventricular septal defect (VSD) is a hole in the heart. It's a common heart problem present at birth (congenital heart defect). The hole occurs in the wall that separates the heart's lower chambers (ventricles). A VSD changes how blood flows through the heart and lungs. Oxygen-rich blood gets pumped back to the lungs instead of out to the body. Webventricular volume, also referred to as active ventricular filling. At rest this "topping off" of the ventricles is of little significance but when we begin to exert ourselves it becomes much more important.
