Excretory System

By: Shelbie Rhodes and Sydney Archibald

What is the function of the Excretory System?

The function of the excretory system is to get rid of wastes such as sweat glands, the liver, the lungs, and the kidney system.

Functions of each organ

The kidneys are bean shaped organs that removes waste from blood, balance body fluids, urine, and help in other organs.

The urinary bladder collects urine excreted by the kidneys before disposal by urination.

The skin protects from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold.

Liver- Production of bile, which helps carry away waste and break down fats in the small intestine during digestion. Production of certain proteins for blood plasma.

Lungs- the oxygen is moved into the bloodstream and carried through the body.


Nephritis- is the inflammation of one or both kidneys. Herein the organs of body get affected through autoimmune disorders. Out of the disorders, lupus nephritis is a potentially serious condition. In this, the auto immune system of the body attacks body tissues, organs and body cells. The result is pain at the start and body organ damage for continued diseases.

Causes: This is caused by the inflammation of the first part of nephron (the basic kidney unit), which is called glomerulus.
