Which Chamber Has the Thickest Wall

Question

Which chamber has the thickest wall?
A) left atrium
B) right atrium
C) left ventricle
D) right ventricle
E) left auricle

Accepted Answer

The left ventricle has the thickest wall among all the chambers of the heart. This is because it is responsible for pumping oxygenated blood to the rest of the body, so it needs more muscular power to do this effectively. The right ventricle has a thinner wall because its job is to pump deoxygenated blood to the lungs, which requires less force than sending blood to the body's tissues.
