The right kidney is found much lower than the left because it has to accommodate the liver, the largest gland in the human body. Each kidney is about 11.25 cm. in length, 5 to 7.5 cm. in breadth, and rather more than 2.5 cm. in thickness. The left is somewhat longer, and narrower than the right. Furthermore, the liver is the only organ in the body that can regenerate a portion of its lost tissue.
