The kidneys are two bean-shaped organs located deep to the 12th rib and extending down to the L2 region of the low back. The outer layer of the kidney is the cortex. The bladder is the storage site for urine. The kidneys filter around 1,000 liters of fluid daily. The urethra delivers urine from the bladder to the external environment.
