During ventricular systole the atria are in
WebCheck all the INCORRECT statements. Isovolumetric contraction starts with the closure of the atrioventricular valves. The ventricle spends more time in diastole than in systole. During the cardiac cycle, the ventricular systole precedes the atrial systole. In the systemic circulation, blood enters the heart through the right atrium. 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 …
