What valve lies between the right ventricle and the pulmonary trunk?

Explanation:
The valve between the right ventricle and the pulmonary trunk is the pulmonary semilunar valve. When the right ventricle contracts, blood is propelled into the pulmonary trunk through this valve, which is part of the semilunar group that guards the outflow tracts from the ventricles and prevents blood from flowing back into the ventricle during relaxation. The tricuspid valve sits between the right atrium and right ventricle, the bicuspid (mitral) valve sits between the left atrium and left ventricle, and the aortic semilunar valve sits between the left ventricle and the aorta.
