WebFeb 12, 2024 · What is the role of blood in gill respiration? Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. The blood capillaries in the gill filaments are close to the gill surface to take up oxygen from the water and to give up excess carbon dioxide to the water. … Webwhere L fil is the total length of all the gill filaments, n lam is the lamellar frequency (i.e., the mean number of lamellae per unit length on one side of a filament, which is multiplied by two to account for lamellae on each side), and A lam is the mean bilateral surface area of a lamella. This classical method of estimating gill area takes advantage of the highly …
