How the two kidneys differ in location and size?

The two kidneys differ in location due to the presence of the liver on the right side of the body, which pushes the right kidney slightly lower than the left. Typically, the left kidney is positioned higher than the right kidney, sitting at about the level of the T12 to L3 vertebrae, while the right kidney sits lower, around the level of L1 to L4. In terms of size, the left kidney is often slightly larger than the right kidney, although the difference in size is generally minimal.
