WebThe period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle ( Figure 19.27 ). The period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The period of relaxation that occurs as the chambers fill with blood is called diastole. WebThe cardiac cycle. The heart relies on its muscle to contract and relax to pump the blood around the body. The left and right sides of the heart are independent of each other, however, will contract synchronously.. When in a contractile state, this is called systole.When in a relaxed state, this is called diastole.. The cycle can then be divided …

There are two stages during the cardiac cycle. During diastole, the ventricles relax and fill with blood. The muscles contract during systole, pushing blood through the arteries. Cardiac Cycle Explained WebFor the average person, the heart rate is 72 beats/minute. Therefore, the length of a single cardiac cycle can be calculated as follows: 1/72 beats / minute = .0139 minutes / beat.
