Expert Answer:

Dear archanasunil2020@gmail.com
 
Answer to your first question is:
The right ventricle pumps the deoxygenated blood to the lungs and the left ventricle pumps the oxygenated blood with great force so that it is supplied to all parts of the body. Hence, the ventricles have thicker walls.
