Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which ventricle has the thickest walls?
A
Left Atrium
B
Right Atrium
C
Left Ventricle
D
Right Ventricle
Explanation: 

Detailed explanation-1: -The left ventricle has the thickest wall out of all the chambers. The left ventricle is responsible for pumping the blood towards the tissues of the heart. This is why more muscles contracting inside the left ventricle helps produce a higher force to move the blood towards the system.

Detailed explanation-2: -The left ventricle pumps blood at higher pressures compared to the rest of the other heart chambers, as it faces a much higher workload and mechanical afterload. In comparison to that of the right ventricle, the free wall of the left ventricle is much thicker.

Detailed explanation-3: -The myocardium is thickest in the left ventricle, as this chamber must create substantial pressure to pump blood into the aorta and throughout systemic circulation.

Detailed explanation-4: -The left ventricle is longer and more conical in shape than the right, and on transverse section its concavity presents an oval or nearly circular outline. It forms a small part of the sternocostal surface and a considerable part of the diaphragmatic surface of the heart; it also forms the apex of the heart.
