MCQ
Solution
As it has to pump pure blood with force.
Explanation:
The right ventricle is only responsible for pumping deoxygenated blood into the lungs via the pulmonary artery, whereas the left ventricle is responsible for pumping oxygenated blood throughout the body via the aorta and its branches. For this, there must be enough power and pressure on the blood output to allow the blood to reach all sections of the body.
