Question

Why are the walls of right auricle
thinner than the walls of the right ventricles ?
PLEASE PROVIDE A CLASS 10 ANSWER

Answer 1

It is because the left ventricle needs to pump blood to different parts of the body, and for this high pressure is applied by the wall of the left ventricle, which requires strength.

Whereas, the right ventricle pumps blood only to the lung for oxygenation, which is very close to the heart, hence very less pressure (in comparison with left ventricle) is required. Thus, the wall of right ventricle is thinner.
