SEMILUNAR VALVE Meaning and Definition

  1. A semilunar valve refers to one of two heart valves that are characterized by a half-moon or crescent shape, hence the name "semilunar." Each semilunar valve is located in the large blood vessels attached to the heart, known as the aorta and the pulmonary artery. The two semilunar valves in the mammalian heart are the aortic valve and the pulmonary valve.

    The aortic semilunar valve separates the left ventricle from the aorta, the main artery that carries oxygenated blood to the rest of the body. It opens when the left ventricle contracts, allowing blood to be propelled out of the heart into the aorta. When the ventricles relax, the aortic valve closes to prevent backflow of blood into the heart.

    The pulmonary semilunar valve, on the other hand, separates the right ventricle from the pulmonary artery, which carries deoxygenated blood to the lungs for oxygenation. It opens when the right ventricle contracts, allowing blood to be pumped into the pulmonary artery. When the ventricles relax, the pulmonary valve closes to prevent the blood from flowing back into the right ventricle.

    Overall, the semilunar valves play a crucial role in maintaining the proper flow of blood through the heart and ensuring that blood moves in the correct direction.

  2. (1) One of the valves guarding the orifice of the aorta (valvulae semilunares aortae or that of the pulmonary artery (valvulae semilunares arteriae pulmonalis; (2) v. of Tarini, velum medullare posterius.
