There are two main atrioventricular valves, each separating a specific atrium and ventricle:
The atrioventricular (AV) valves are the heart's specialized "gatekeepers" that ensure blood flows in only one direction—from the upper chambers (atria) to the lower chambers (ventricles). They are critical for efficient heart function, opening to fill the heart with blood and closing tightly to prevent backflow. atrioventricular valve
: Located on the right side of the heart, it typically consists of three leaflets (flaps). It controls blood flow between the right atrium and right ventricle. There are two main atrioventricular valves, each separating
