lo 3.1. which side of the heart has a thinner wall, and why?
the right side of the heart has a thicker wall because it pumps blood to the lungs to be oxygenated.
the left side of the heart has a thinner wall because it only pumps blood to the body.
both sides of the heart have the same thickness of the wall.
the left side of the heart has a thicker wall because it pumps blood to the body.
the right side of the heart has a thinner wall because it only pumps blood to the lungs.

Explanation:

The right side of the heart pumps blood to the lungs (pulmonary circulation), which is a shorter distance with lower resistance. The left side pumps blood to the entire body (systemic circulation), requiring more force and thus a thicker wall. So the right side has a thinner wall as it only pumps to the lungs.

Answer:

The right side of the heart has a thinner wall because it only pumps blood to the lungs.
