Human urinary system is the body' organ system which performs the function of removal of liquid waste from the body. It consists of the following parts:
1) Kidneys: A pair of kidneys are the main organs of the urinary system. There function is to filter blood and eliminate the waste in the form of urine. Kidneys contain millions of small filtering units called nephrons. Impure blood enters the kidneys through renal arteries. It enters the nephrons, where the blood is filtered and wastes are removed in the form of urine. The pure blood then leaves the kidney through renal vein. 
2) Ureter: These are the tubes which carry urine from the kidneys to the urinary bladder.
