endocrine system (notes)

  1. maintain homeostasis
  2. respond to stimuli
  3. regulate body development
  • hormones (chemicals) released into body by endocrine organs to send messages through body
  • glucose concentration in blood must be kept w/in constant range
-can't be too low or no glucose for cellular respiration --> weak, tired, shakey, etc.
- can't be too high bc dangerous

glucose can be stored as glycogen <--can be broken down into glucose in bloodstream by enzymes
  • insulin: hormone from pancreas, released when blood sugar is too high 
-binds to muscle & fat cells to increase uptake of glucose from blood
-binds inside liver & tells it to convert glucose to glycogen
