EXCRETORY SYSTEM

The Excretory System is responsible for the elimination os wastes produced by homeostasis.

There are several parts of the body thar are involved in this process, such as sweat glands, the liver, the lungs and the kidney system.

Every human has two kidneys on the left and right sides of the body in vertebrates. They are located at the back of the abdominal cavity. Although the kidneys are the main organs of excretion, the skin, lungs and liver also help in excretion. Our skin has sweat glands, through which we excreted small amounts of water,urea and salts.

The systems are coordinated by the nervous and endocrine systems. The nervous system detects stimulates and answers it by sending nerve impulses to different parts of the body, activating or stopping some of their functions.
