Question

Quizplus · Accepted Answer

At the end of ventricular isovolumic relaxation, the pressure in the left ventricle drops below the pressure in the left atrium, causing the mitral valve (also known as the atrioventricular valve) to open and allow blood to flow from the left atrium to the left ventricle. This is the beginning of ventricular filling. The aortic valve remains closed during this phase.
