WebWhat happens during the cardiac cycle? A single cycle of cardiac activity can be divided into two phases - systole and diastole. The cardiac cycle is then further divided into three stages - atrial systole, ventricular systole, and ventricular diastole. Below is a diagram that shows the big picture of the cardiac cycle events. WebAll steps. Final answer. Step 1/2. 1. During ventricular systole, the ventricles of the heart contract to pump blood into the aorta and pulmonary artery. This phase is divided into two stages one is isovolumetric contraction and the other is ventricular ejection. View the full answer. Step 2/2. Final answer.

WebSep 19, 2024 · The Cardiac Cycle. The cardiac cycle can be divided into four stages:. Filling phase – the ventricles fill during diastole and atrial systole.; Isovolumetric contraction – the ventricles contract, building up …

WebIsovolumetric 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. The end-diastolic volume WebAt the same time, there is a corresponding decrease in arterial blood pressure to its minimum (diastolic blood pressure), normally about 80 mm of mercury in humans. Ventricular diastole again occurs after the blood has been ejected (during ventricular systole) into the aorta and pulmonary artery.
