Answer 1

Answer:

Here's Your Answer

Explanation:

The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body. ... Both the atria and the ventricles undergo alternating states of systole and diastole.

The cardiac cycle involves four major stages of activity: 1) "Isovolumic relaxation", 2) Inflow, 3) "Isovolumic contraction", 4) "Ejection".

Answer 2

Cardiac Cycle Phases

Atrial Systole: At this phase, blood cells flow from atrium to ventricle and at this period, atrium contracts. Isovolumic Contraction: At this stage, ventricles begin to contract. ... Ventricular Ejection: Here ventricles contract and emptying. Pulmonary artery and aortic valve close.
