- - - - diffusion
        
        most common
      - filtration
      - osmosis
    - - higher needs(brain,muscle)= moreelaberate networking
      - lower cellular needs=less branching
  - - - vasodilation=increases vessel volume= increased blood flow= decreasedblood pressure
        
        vasoconstriction(contraction) = decreased vessel volume- decreased blood flow=increased blood pressure
  - - - with the aid of contraction of skeletal muscles
      - with the aid of changes in cavity pressure
      - because the pressure in the veins is lower than the arteries
- - - - the third and forth heart sounds
  - - - pressure differences
      - the viscosity of the blood
      - the amount of friction in the blood vessel
- - - - 10-12%
    - - 8-11%
    - - 10-12%
    - - 4-5%
    - - 60-70%
- - - - filtration
      - osmosis
      - diffusion
- - - - decreased urine formation
      - rapid, weak pulse
      - hypotension
      - acidosis
- - - - EN
      - e
      - EPO
      - adosterne
      - angiotension
  - - - increased levels of ANP(atrialnatriuretic peptide)
    - - ANP
      - histamine
  - - - stroke volume
      - heart rate
      - blood pressure
