The _______ valve separates the left atrium from the left ventricle.
mitral
The valve that separates the left atrium from the left ventricle is the mitral valve, also known as the bicuspid valve. It consists of two cusps that open and close together, allowing blood to flow from the left atrium to the left ventricle during diastole, and preventing backflow of blood into the left atrium during systole. The mitral valve is important for maintaining normal blood flow and preventing blood from flowing backward in the heart’s circulation. Any abnormality in the mitral valve can lead to a condition known as mitral regurgitation, in which blood leaks backward into the left atrium, potentially causing symptoms such as shortness of breath, coughing, and fatigue.
