The left ventricle, being responsible for pumping the blood through the systemic circulation, generates the highest pressures. For this reason, the left ventricle has the thickest muscular walls.

The left ventricle. The muscle must be much stronger in this chamber because it propels blood out into the systemic circuit. The right ventricle only has to pump blood through the lungs and the atria only have to empty into the ventricles.

The thickest layer of the heart by far is the myocardium, which is the muscle of the heart. The other two layers are the pericardium and the endocardium, both of which are just a few cell layers thick.
