Diffusion of o2 in water
WebCountercurrent gas exchange in the gills of a fish a. maintains a gradient that enhances diffusion. b. enables the fish to obtain oxygen without swimming. c. means that blood and water flow at different rates. d. allows O2 to diffuse against its partial pressure gradient Verified Solution WebBlood is pumped to the lungs to be oxygenated before being pumped to the rest of the body. The circuits increase the amount of surface area available for the diffusion of gases and nutrients in the body. Land vertebrates are bigger and require more tubing to reach all areas of the body. The large decrease in blood pressure as blood moves ...
