Web17 okt. 2024 · The cardiac cycle is the sequence of events that occur in the heart with each beat. In this cycle, blood is pumped out of the heart and oxygen is circulated around the body. As the ventricles relax from the previous cycle, blood passively flows into the ventricles from the atria through the open atrioventricular (AV) valves. Web8 jun. 2024 · Closing of the semilunar valves produces a monosyllabic “dup” sound. Figure 40.11. 1: Diastole and systole: (a) During cardiac diastole, the heart muscle is relaxed and blood flows into the heart. (b) During atrial systole, the atria contract, pushing blood into the ventricles. (c) During atrial diastole, the ventricles contract, forcing ...
