Homeostasis

• What is homeostasis?

  The regulation of the internal conditions of a cell or organism in response to internal or external changes
• Why is homeostasis important?

  It keeps conditions constant for enzyme action and cell functions
• Homeostasis includes the control of:

  -blood glucose concentration

  -body temperature

  -water and ion levels
• What may the control systems of homeostasis involve?

  -responses using nerves

  -chemical responses using hormones
• What is homeostasis?

  • The maintenance of steady conditions in the body
  • Involves keeping internal environments constant, such as temperature and blood glucose concentration
• What conditions must be kept constant in mammals for homeostasis?


  Water concentration, temperature, and glucose concentration
