Endocrine System (NEGATIVE FEEDBACK (Homeostasis maintained by internal…

- - - - Regulates various body functions, including other endocrine glands
      - MOST IMPORTANT ENDOCRINE GLAND
    - - Act on tissue, rather that specific organs
      - HUMAN GROWTH HORMONE
        
        Regulates the body's physical growth by stimulating cell division in the muscle / tissue
        
        Especially active during childhood / adolescence
  - - - THYROXINE HORMONE
        
        Does not act on specific organs
        
        Causes cells of the body to have a higher rate of metabolism
      - CALCITONIN HORMONE
        
        Partly responsible for the regulation of calcium
        
        Essential mineral for bone formation / blood clotting / nerve function / muscle contraction
        
        Lowers blood calcium levels by signaling bones to increase calcium absorption / kindneys excrete more calcium
    - - PARATHYROID HORMONE
        
        Increases blood calcium levels by stimulating the bones to release calcium
        
        Causes the kidneys to reabsorb more calcium / intestines absorb more calcium from food
  - - - Outer part
      - Manufactures the steroid hormone / glucorticoids (group of hormones)
    - - Afefcts the kidneys
      - Reasorbtion of calcium
    - - Glucorticoid
      - Raises blood glucose levels
      - Reduces inflammation
- - - - Produce hormones
      - Released into the bloodstream
      - Distributed to body cells
- - - - 20 years old
      - Cannot produce insulin
    - - 70 - 80 % of the people diagnosed with diabetes
      - After 40 years old
      - Results from the cells becoming insensitive to insulin
    - - Coronary heart disease / retinal damge / nerve damage / acidosis / low blood pH
