ANATOMY

Detailed explanation-1: -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. The semilunar valves are made up of connective tissue and a thin smooth membrane known as the endocardium.

Detailed explanation-2: -The valve between the left ventricle and the aorta is the aortic semilunar valve. When the ventricles contract, atrioventricular valves close to prevent blood from flowing back into the atria. When the ventricles relax, semilunar valves close to prevent blood from flowing back into the ventricles.

Detailed explanation-3: -The semilunar valves determine the passage of blood between the ventricles and the main arteries, transporting blood away from the heart to the vital organs.

Detailed explanation-4: -What is the function of a semilunar valve? The function of a semilunar valve is to carry the blood to the distant parts of the body. It also prevents the flow of blood from the aorta and pulmonary artery to the ventricles of the heart.

Detailed explanation-5: -The atrioventricular valves prevent backflow of blood into the atria during ventricular contraction (systole), and the aortic/pulmonic (semilunar) valves prevent backflow of blood into the ventricles during ventricular relaxation (diastole).
