As stated before, each kidney is four inches long, two to two and one-half in breadth, and more than one inch thick. The left is somewhat longer, though narrower, than the right. The kidney is covered with what is called a capsule. This can be easily stripped off. The structure of the kidney is quite intricate. At the inner border of each kidney there is an opening called the pelvis of the kidney, and leading from this, small tubes penetrate the structure of the kidney in all directions. These tubes are lined with special cells. Through these tubes go the excretions (urine) from the body of the kidneys, to the pelvis, and from the pelvis through the ureters, sixteen inches long, to the bladder.
