What is another name for the mitral valve?

Explanation:
The name mitral valve is also used for the bicuspid valve because it has two leaflets. “Bi-” means two and “cuspid” refers to the leaflets of a valve, so bicuspid valve is a historic and still-used synonym for the mitral valve. This valve sits between the left atrium and left ventricle and prevents backflow during ventricular contraction. The other valves mentioned are not synonyms: the tricuspid valve is the right-side atrioventricular valve; the aortic valve and the pulmonary valve are semilunar valves at the exits of the heart, named for their positions and functions rather than as synonyms for the mitral valve.
