bicuspid valve

A Dictionary of Biology | 2004 | Copyright

bicuspid valve (left atrioventricular valve; mitral valve) A valve, consisting of two flaps, situated between the left atrium and the left ventricle of the heart of birds and mammals. When the left ventricle contracts, forcing blood into the aorta, the bicuspid valve closes the aperture to the left atrium, thereby preventing any backflow of blood. The valve reopens to allow blood to flow from the atrium into the ventricle. Compare tricuspid valve.
