State three differences between the right and left sides of the mammalian heart.

Oxygen Levels: The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The left side of the heart, on the other hand, receives oxygenated blood from the lungs and pumps it to the rest of the body.

Thickness of the Walls: The walls of the left side of the heart, particularly the left ventricle, are much thicker than those of the right side. This is because the left side needs to generate a greater pressure to pump blood to the entire body, while the right side only needs to pump blood to the lungs.

Valves: The right side of the heart has the tricuspid valve that separates the right atrium and the right ventricle, while the left side has the mitral or bicuspid valve between the left atrium and the left ventricle. The pulmonary valve is present on the right side leading to the pulmonary artery, and the aortic valve is on the left side leading to the aorta.
