Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in … WebIt is not a one-way ventilation system. You breathe in and out; it is 2 times. The diffusion gradient is provided by new air/ freshly pumped blood, not a CC. Fish can only have a one way ventilation system, so they need something (i.e. a CC system) else to provide a diffusion gradient. Reply 3 15 years ago OP Thank you :] toy crank handle
