Gas Exchange and Transport
  1. Resting Oxy consumption=250mL min-1
    1. Produce 200mL min-1 of CO2
    2. Direction of exchange of Oxy
      1. Lungs, 02 diffuse from alveoli to capillary blood
        1. Systemic cap beds, 02 from blood to cells via interstitial fluid
          1. C02 opp direction
          2. Dalton's Law
            1. Total P= P1+P2+P3 etc ( total of all gases in same vol)
            2. Alveolar Air
              1. Atmospheric air inhaled...
                1. saturated with water vapour
                  1. mix with air with high CO2 in resp' dead space
                2. Higher PCO2 + lower P02 than atmo air
                3. Rate of gas diffusion
                  1. Directly proportional to
                    1. conc grad across memb
                      1. surf area of memb
                        1. Permeabilty of memb to the gas
                        2. Inversely prop to
                          1. thickness of memb
