Introduction to Kidneys and Osmoregulatory Organs

Describe the structure of the kidneys and the functions of the parts of the kidney

Although the kidneys are the major osmoregulatory organ, the skin and lungs also play a role in the process. Water and electrolytes are lost through sweat glands in the skin, which helps moisturize and cool the skin surface, while the lungs expel a small amount of water in the form of mucous secretions and via evaporation of water vapor.
