Answer Details
The chamber of the mammalian heart with the thickest wall is the left ventricle. This is because the left ventricle is responsible for pumping oxygen-rich blood to the rest of the body, so it needs to generate more forceful contractions than the other chambers. The thick wall of the left ventricle is made up of strong muscle tissue that allows it to contract with enough force to push blood through the systemic circulation, which is the circulation of blood throughout the body. The right ventricle, on the other hand, has a thinner wall because it only needs to pump blood to the lungs, which are nearby and don't require as much force.
