Quizplus · Accepted Answer

The right and left ventricles can be distinguished by the thickness of their walls. The right ventricle has a thinner wall than the left ventricle due to the fact that it only pumps blood to the lungs, while the left ventricle has a thicker wall to pump blood to the rest of the body. A, B, and C are not specific enough to distinguish between the right and left ventricles.
