Homeostasis

• Homeostasis is the ability to maintain a relatively stable internal environment, independent of any changes happening in the external environment
• Homeostasis controls body temperature, ion concentration, chemicals, water content, blood glucose levels
• Messages are carried around the body by the nervous system or by hormones produced by the glands of the endocrine system 
• Stages of Homeostasis

  1. The body detects a change from the stable state, in either the internal or external environment
  2. These changes are counteracted by responses in the body
