Why does the right kidney sit lower than the left kidney?

• A. The left kidney is anatomically higher due to its intrinsic position
• B. The spleen displaces the left kidney downward
• C. The liver displaces the right kidney downward
• D. The stomach sits above the right kidney

Answer: (C)

The right kidney sits lower because the liver, which is large and occupies much of the right upper abdomen, pushes it downward. Since the liver dominates the right side, it lifts space constraints and causes the right kidney to be positioned a bit lower than the left. The left side isn’t similarly pushed down by a large organ; the spleen and stomach are nearby but don’t exert the same downward pressure, so the left kidney remains comparatively higher. In short, the liver’s size and position on the right side is the main reason for the asymmetrical kidney heights.
