The mitral valve is one of the four heart valves and is located between the left atrium and the left ventricle of the heart. Its primary function is to ensure unidirectional blood flow from the left atrium to the left ventricle, preventing backflow when the heart contracts.Key Features:Structure: The mitral valve has two leaflets, or cusps, making it a bicuspid valve. These leaflets are called the anterior and posterior leaflets.Supporting Structures: The valve is supported by the chordae tendineae, thin tendons that anchor the leaflets to the papillary muscles in the left ventricle. These prevent the valve from inverting when the ventricle contracts.Function: During diastole (the heart’s relaxation phase), the mitral valve opens to allow oxygen-rich blood from the left atrium to fill the left ventricle. During systole (the contraction phase), it closes to prevent blood from
