In the human body, the production of energy from food also results in the production of waste. The bi-products of numerous chemical and physiological processes that are no longer required by the human body must be disposed of.
The human excretory system is a collection of organs that eliminate waste products from the human body.
Urea is the most common waste product produced by the human body.
Urination is the process by which urea is removed from the body in the form of a liquid by the kidneys.
The following are the primary organs of the human excretory system:
Kidneys: The kidneys are bean-shaped organs that are protected by the ribs and back muscles and are located on either side of the backbone. Urine output is primarily their responsibility.
Ureter: A narrow and muscular tube connects each kidney to the renal pelvis. The Ureter is the name for this tube. The ureter's job is to periodically transport urine from the kidneys to the urinary bladder.
Urinary Bladder: The urinary bladder is the organ that regulates urine flow. It is a muscular sac-like structure that holds urine above the pubic bone.
Urethra: The urethra is a fibro-muscular tissue tube that emerges from the lower aperture of the urinary bladder, travels through the urogenital and pelvic diaphragms, and exits the body through an external urethral orifice. It facilitates the elimination of urine from the body.
