What are 3 ways that exchange surfaces are adapted to their function? Gills in fish Exchange of gases in fish is very efficient because of: the large surface area of the gills. maintains diffusion / concentration gradient / equilibrium not reached; Describe and explain how fish maintain a flow of water over their gills. Summary. This system maximises the amount of oxygen diffusinginto the blood by having the most oxygenated blood meet the most oxygenated water, and the least oxygenated blood meet the least oxygenated water. The gills' large surface area tends to create a problem for fish that seek to regulate the osmolarity of their internal fluids. Fish breathing Adaptations for Gas Exchange Mouth & Opercula Alternate opening of the mouth and two flaps of skin that cover the gills called the opercula (singular: operculum) helps to force water across the gill surface = ventilate the gas exchange surface.
