Video Summary:
At the time of opening of the mitral valve, the ventricular volume is about 50 ml and pressure is about 7 mmHg. This is followed by ventricular filling, which ends at the closure of the mitral valve. At this point, the volume has increased and reached the end-diastolic volume of about 120 ml. During this, initially, there is a slight fall in pressure, and later there is a slight rise. In the end, the pressure is about 10 mmHg. Then the mitral valve closes and isovolumetric contraction begins. There is no change in volume so we have 120 ml of blood in the ventricle, but pressure rises to about 80 mmHg. At this point, the aortic valve opens. This is followed by the ejection of blood. So the volume decreases and reaches the end-systolic volume of about 50 ml. During this, initially, there is a rise in pressure as ventricular musculature continues to contract. The maximum pressure reached is about 120 mmHg. Then, as the muscles start relaxing, there is a fall in pressure. In the end, the pressure is about 100 mmHg At this point the aortic valve closes. This is followed by isovolumetric relaxation. During this, there is no change in volume but pressure falls to about 7 mmHg. Thus the entire cycle is completed. The area covered by this loop represents the net external work output of the ventricle.
