Homeostasis is the regulation of internal environment in humans and animals.
Their are principally 6 substances that the body has to control:
This control is achieved by the use of various organs and glands in the body.
The hypothalamus monitors water-contents, carbon dioxide concentration and blood temperature, sending nerve impulses to the pituitary gland and skin.
The pituitary gland makes ADH (Anti-diuretic hormone) to control water content in the body.
The muscles can shiver to produce heat if body temperature is too low.
The pancreas produces insulin to control blood-sugar concentration.
The lungs take in oxygen and give out carbon dioxide.
The kidneys remove urea and adjust ion and water concentration.
