Q. To which heart chamber does the blood go after leaving the left atrium? What is the valve that separates these compartments?
The valve between the left atrium and the left ventricle is the mitral valve a bicuspid (two leaflets) valve. The mitral valve is important because it prevents the regurgitation of blood to the left atrium during systole that is contraction of the ventricles, the arterial blood that has come from the lungs to the left atrium passes then to the left ventricle.
