ventilrörelser
Ventilrörelser refers to the coordinated movements of the heart valves that regulate blood flow through the heart. These movements are crucial for ensuring that blood flows in one direction, preventing backflow and maintaining efficient circulation. The two primary phases of the cardiac cycle, diastole and systole, are defined by these valve actions.
During diastole, the heart muscle relaxes, and the atrioventricular valves, the mitral valve between the left
Systole is the phase of ventricular contraction. As the ventricles begin to contract, the pressure within them
