Homeostasis = Maintaining a stable internal environment
Osmoregulation = Regulating water content - balance the amount gained and lost
Thermoregulation = Regulating body temperature - get rid of excess heat but retain when cold
Blood glucose regulation = Keep glucose in the blood at a steady level
A mechanism called negative feedback helps keep things steady:
- Changes in environment trigger a response that counteracts the changes
- So internal environment stays at a norm
- Only works with certain limits
