ANATOMY

Detailed explanation-1: -The semilunar valves act to prevent backflow of blood from the arteries to the ventricles during ventricular diastole and help maintain pressure on the major arteries. The aortic semilunar valve separates the left ventricle from the opening of the aorta.

Detailed explanation-2: -The semilunar valves permit blood to flow into the arteries from the ventricles and prevent the backward flow of blood from the arteries into the ventricles.

Detailed explanation-3: -Aortic valve: Allows blood to pass from the left ventricle to the aorta; prevents backflow of blood into the left ventricle.

Detailed explanation-4: -The atrioventricular (AV) valves prevent backflow of blood into the atria during ventricular contraction (systole), and the aortic/pulmonary (semilunar) valves prevent backflow of blood into the ventricles during ventricular relaxation (diastole).

Detailed explanation-5: -The mitral valve also known as bicuspid valve is located in the left side of the heart, between the left atrium and left ventricle. It prevents the back flow of blood from left ventricle to left atrium during ventricular systole.
