प्रश्न
Right ventricular wall is thinner than the left ventricular wall. Why?
Advertisements
उत्तर
The right ventricle pumps deoxygenated blood, to the lungs through the pulmonary artery. The left ventricle pumps the oxygenated blood to all parts of the body through the aorta. Hence, the left ventricle has to exert more pressure. Hence the right ventricular wall is thinner but the left ventricular walls are thicker.
