Extra Insights
During atrial systole, the atrioventricular (AV) valves, like the mitral and tricuspid valves, are actually open to allow blood to flow from the atria into the ventricles. This phase is crucial for filling the ventricles with blood before they contract in the next phase of the heartbeat. So, the statement is False!
In fact, the coordination of the heart’s contractions is a marvel of timing, ensuring that blood flows efficiently. If the AV valves were closed during this phase, it could lead to improper blood flow and potentially dangerous conditions. That’s why our heart has evolved such a clever mechanism to keep everything running smoothly!
