The Human Urinary System

Diagram of the Human Urinary System (Infographic) The kidneys are the primary organs of the urinary system. They remove urea – a waste product formed by the breakdown of proteins – from the blood through filtering units called nephrons. A normal, healthy bladder can hold up to 16 ounces (almost half a liter) of urine comfortably for 2 to 5 hours.

How the human body’s urinary system works. The urinary system – also known as the renal system – produces, stores and elimiates urine, the fluid waste excreted by the kidneys. The system works with the lungs, skin and intestines to maintain the balance of chemicals and water in the body. The kidneys are the primary organs of the urinary system.

Urinary System Function. The main urinary system function is to filter the blood of excess water, salts, and waste products, temporarily store these within a reservoir, and intermittently expel these products from the body. Each kidney contains approximately one million nephrons.
