WebAlveoli in the lungs, fish gills and the villi in the small intestine are adapted so that they have short diffusion distance, big concentration difference and large surface area. WebThe gill is also the site of Na + /Na + and Cl-/Cl-exchanges which involve 25 to 75 % of the internal NaCl per hour. The relative importance of simple diffusion and exchange-diffusion in these exchanges is assessed. Biochemical studies reveal two enzymes playing important roles in the ionic pumps: carbonic anhydrase and Na-K activated ATPase.
