- These bean-shaped organs are located in the retroperitoneal space, behind the peritoneum lining the abdominal cavity.
- The right kidney is slightly lower than the left, due to the position of the liver on the right side.
- The kidneys are located between the 11th and 12th ribs, behind and beneath the lower ribs.

- Urine travels from the kidneys through the ureters to the bladder, and then out of the body through the urethra.
