ANATOMY

Detailed explanation-1: -semilunar valve, either of two pocketlike half-moon-shaped structures located between the left ventricle and the aorta (aortic valve) and between the right ventricle and the pulmonary artery (pulmonary valve ) of the heart.

Detailed explanation-2: -The aortic and pulmonary valves are semilunar valves which separate the ventricles from the aorta and pulmonary artery, respectively.

Detailed explanation-3: -The semilunar valves are half-moon-shaped leaflets of endocardium and connective tissues, situated between the aorta and the left ventricle and between the pulmonary artery and the right ventricle. These valves permit blood to be forced into the arteries, but prevent backflow from the arteries into the ventricles.

Detailed explanation-4: -There are two semilunar valves: the aortic semilunar valve that is defined as the valve that protects the point of attachment between the aorta and the left ventricle in the heart and the pulmonary semilunar valve that is defined as the valve located between the pulmonary artery and the right ventricle of the heart.

Detailed explanation-5: -The aortic and pulmonic valves are known as the semilunar valves, whereas the tricuspid and mitral valves are referred to as the atrioventricular valves.
