Answer 2

Ventricles of the heart have thick walls due to the following reason:

Explanation:

• When the ventricles contract, the blood is pumped from the heart to all the parts of the body.

• Hence, the walls of the ventricles have to be thick enough to maintain the blood pressure inside it and force the blood out of it into the blood vessels.

• Higher forces are required to pump blood into the systematic circuit and hence thick walls are required to maintain this pressure.
