Which valve separates the left ventricle from the aorta?

Explanation:
This question tests knowledge of which valve sits at the junction of the left ventricle and the main artery leaving the heart. The left ventricle pushes oxygen-rich blood into the aorta through the aortic valve. This valve opens during contraction to allow blood into the aorta and closes to prevent backflow into the ventricle. The other valves have different roles: the pulmonary valve is between the right ventricle and the pulmonary artery; the mitral valve lies between the left atrium and left ventricle; the tricuspid valve sits between the right atrium and right ventricle.
