Final answer:
The correct term for a semilunar valve that has the right ventricle on one side is the pulmonary valve, which corresponds to option D. This valve prevents backflow of blood into the right ventricle and consists of three flaps.
Step-by-step explanation:
A semilunar valve that has the right ventricle on one side is known as the pulmonary valve. Therefore, the correct match for the given term would be D. pulmonary valve.
The pulmonary valve, also referred to as the pulmonary semilunar valve, the pulmonic valve, or the right semilunar valve, is located at the base of the pulmonary trunk and it prevents backflow of blood into the right ventricle. It consists of three small flaps of endothelium reinforced with connective tissue which close when the right ventricle relaxes, preventing the backflow of blood from the pulmonary trunk into the ventricle.
Just for clarity, the other valves mentioned function differently: The tricuspid valve is an atrioventricular valve that sits between the right atrium and right ventricle, the bicuspid or mitral valve is the atrioventricular valve between the left atrium and left ventricle, and the aortic valve is the semilunar valve that sits at the junction of the left ventricle and the aorta.
