lo 3.1. which side of the heart has a thinner wall, and why?
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 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.
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, which are relatively close and require less force. The left side pumps blood to the entire body, which is a longer distance and requires more force, so its walls are thicker.

Answer:

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