Diastole And Systole Research Paper

Diastole and systole
Diastole is the phase of the heart’s cycle where a chamber of the heart, either an atrium or ventricle, relaxes and fills with blood. Also called the relaxation phase. The two top chambers relax and fill with blood. The ventricles are also relaxed and the blood flows from the atrium to the ventricles during this time. While systole is the phase of the heart’s cycle when the ventricles contract to eject blood from within the chamber. The two top chambers contract, followed by ventricular contraction. There are two steps. Within this first step, the atria contract together to push the blood down into the ventricles (diastole). In the second step, the two ventricles contract to force the blood out of the heart (systole). The
