Homeostasis

• Homeostasis is the regulation of the internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes
• Homeostasis is important because it maintains optimal conditions for enzyme action and all cell functions.
• Control of blood glucose concentration, control of body temperature and control of water levels in the human body are examples of homeostasis
• An organism maintains homeostasis by monitoring its internal conditions and responding appropriately when these conditions deviate from their optimal state
• These automatic control systems may involve nervous responses or chemical responses. Many of the processes are coordinated by hormones
