The urinary systems consists of a pair of kidneys, a pair of ureters, a urinary bladder, and a urethra.
The kidney is a reddish, bean-shaped organ found above the peritoneum and the posterior wall of the abdomen. The right kidney is slightly lower that the left because the liver occupies considerable space on the right side above the kidney.
Found in the kidneys are numerous nephrons, the functional units of the kidneys. Each nephron consists of renal corpuscle, where filtration occurs, and a renal tubule, a passageway for filtered fluid.
