mitraaliläppä

Mitraaliläppä is the Estonian term for the mitral valve, one of the four valves in the human heart. It is located between the left atrium and the left ventricle. The mitral valve is also known as the bicuspid valve because it has two leaflets, or cusps. Its primary function is to ensure that blood flows in only one direction through the heart, preventing blood from flowing backward from the left ventricle into the left atrium during ventricular contraction (systole).

During diastole, when the ventricle relaxes, the mitral valve opens, allowing oxygenated blood to flow from the left atrium into the left ventricle. As the left ventricle begins to contract to pump blood to the rest of the body, the mitral valve closes tightly. This closure is crucial for maintaining efficient blood circulation and oxygen delivery to the body.

Problems with the mitral valve can lead to various medical conditions. Mitral regurgitation occurs when the valve does not close properly, allowing blood to leak backward into the left atrium. Mitral stenosis is a condition where the valve opening narrows, restricting blood flow from the left atrium to the left ventricle. These conditions can strain the heart and may require medical intervention, such as medication or surgery, depending on their severity. Understanding the role and function of the mitraaliläpp is essential for comprehending cardiovascular health.
