- - - - give hypothalamus early warning
  - - - traps air
    - - Reduces heat loss by evaporation
    - - involuntary contraction of skeletal muscle, generating heat
    - - cause increase in metabolic rate and heat production
    - - contraction of arteriole walls that supply blood to capillaries near skin
  - - - arteriole walls relaxes, allows more blood flow and increase loss of heat to surroundings
    - - less air trapped, less insulation, more heat lost
    - - sweat produced causes more energetic molecules to escape and carry heat away
- - - - water lost from descending limb
      - loss of water concentrates Na+ and Cl
      - increase concentration of ions
      - this concentrates the fluid inside the loop so ions passively move down
      - Na+ and Cl- are actively transported out of higher end
    - - 1st part the same way as ascending limb
      - 2nd part the same way as collecting duct
    - - fluid in ascending limb dilute
- - - - autoimmune disease
      - lack of gene that codes for insulin
      - solution: insulin injections and mini pumps
- - - - Detect Stimul
        
        Water Potential
        
        Temperature
        
        pH of blood
    - - Parts
        
        Muscle
        
        Glands
      - Coordination System
        
        Nervous System
        
        Endocrine system
  - - - keep factors within narrow limits making close to set point
      - Factors increase, effector stimulated that makes factor decrease, vice versa
    - - not used to keeping conditions constant
      - useful in other areas: transmission of nerve impulses
- - - - increase light intensity
      - low CO2 concentration
    - - Darkness
      - high CO2 concentratons
      - High temperature
      - Low humidity
      - Water stress
