Explanation:
Detailed explanation-1: -The mitral valve opens, signifying the beginning of ventricular filling where the high pressure from the blood vessels forces blood into the expanding ventricle. After the ventricle fills and transitions to contracting, the pressure eventually exceeds that of the blood vessels.
Detailed explanation-2: -The right and left ventricles then contract, pulling the valves into a closed position and pumping oxygenated blood to the body’s organs and tissues and deoxygenated blood to the lungs for oxygenation.
