The left atrioventricular valve is also known as which valve?

The left atrioventricular valve is the mitral valve, also called the bicuspid valve. It sits between the left atrium and left ventricle and functions to allow blood to move from the atrium into the ventricle while preventing backflow when the ventricle contracts. It’s termed mitral or bicuspid because it has two cusps (leaflets). This distinguishes it from the tricuspid valve on the right side, and from the semilunar valves—the pulmonary valve and the aortic valve—which are located at the exits of the heart rather than between an atrium and ventricle.
