Valve, bicuspid
One of the four valves of the heart, this one is situated between the left atrium and the left ventricle. It permits blood to flow one way only, from the atrium into the ventricle. The valve is more commonly called the mitral valve because its two flaps (cusps) makes it look like a bishop’s miter or headdress.
