Excerpt
Humans are normally born with two kidneys, which are organs that look like kidney beans. Each kidney is usually about four to five inches long and three inches wide. They are located in the lower back near the twelfth rib, and there is one on each side of the spine. The right kidney is just below the liver, the left below the diaphragm and next to the spleen. Due to the right kidney being just below the liver, the right kidney is placed a bit lower than the left one.
