Detailed explanation-1: -The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves. The right atrioventricular valve is the tricuspid valve.
Detailed explanation-2: -It is also called aortic semilunar due to its semilunar shape. It is between the left ventricle and the aorta to ensure that oxygen-rich blood does not flow back into the left ventricle.
Detailed explanation-3: -The aptly named atrioventricular heart valves are situated between the atria and ventricles and are oriented such that their leaflets open by protruding into the ventricles as the heart rests during diastole, allowing blood to fill the ventricular chambers.
