Discuss the events of the cardiac cycle.

The events of the cardiac cycle are arranged in a sequence that reflects a series of pressure changes. Thus, they start with the contraction of the atria and, consequently, the ventricles in one’s body. In this way, the left and the right heart are separated and begin functioning as two circuits. Then, in the continuation of this process, both parts act similarly.

At the stage of diastole, ventricular filling occurs, and during systole, the process is referred to as ventricular contraction. The former’s events include closing the aortic valve, which is followed by the closure of the mitral valve. In turn, the latter is presented by the opposite process, which happens in the mitral valve and then in the aortic valve. In this way, the blood is forced into the arteries due to the increasing pressure.
