Detailed explanation-1: -A semilunar valve is the heart valve at the base of the aorta and the pulmonary artery, and consisting of cusps or flaps that prevent the backflow of the blood during systole. Semilunar valves are paired valves of the heart at the bases of the aorta and the pulmonary artery.
Detailed explanation-2: -Pulmonary valve. The pulmonary valve is located between the right ventricle and the pulmonary artery.
Detailed explanation-3: -The semilunar valves are located at the connections between the pulmonary artery and the right ventricle, and the aorta and the left ventricle. These valves allow blood to be pumped forward into the arteries, but prevent backflow of blood from the arteries into the ventricles.
Detailed explanation-4: -Your pulmonary valve and your aortic valve are the two semilunar valves of your heart. They have this name because their leaflets (flaps) look a bit like crescent moons. Semilunar valves are the passageways between your heart’s ventricles (lower chambers) and arteries.
Detailed explanation-5: -Final answer: The valve that is present at the base of the aorta is called the aortic valve.
