Document Summary

Elasmobranch fish (dog fish; slide 32: carbonic anhydrase is present, membrane bound in the gill and floating around in the plasma, this means that the plasma reactions are catalyzed, this plasma reaction is catalyzed, meaning it occurs quickly playing an important role in co2 excretion, the red cells become less important b/c these fish lack the haldane effect, hb is a good buffer but in the absence of the haldane effect the contribution of hemoglobin to proton binding is lessened, conclusion, there less room in the blood cell to mop up protons and there are catalyzed co2 reactions in the plasma. Internalized invaginated, highly folded infolding of body surface: all three of these gas exchange organs have a series of design features, high surface area, high permeability, thin membranes and richly vascularized surface (lots of blood vessels, fick equation=mo2= po2 x ko2 x sa/t, the respiratory medium has a big impact on the design of the gas exchange organ itself.
