Gas exchange of fish

WebFish use gills for gas exchange. Gills have numerous folds that give them a very large surface area. The rows of gill filaments have many protrusions called gill lamellae. The folds are kept supported and moist by the water that is continually pumped through the mouth and over the gills. Fish also have an efficient transport system within the ... WebSince fish live in water, which has a lower concentration of oxygen in it than air, it requires more of the fishes resting energy to be used for gas exchange, over 10%, which is higher compared to mammals and insects who take in air to get oxygen, mammals use 1-2% of resting energy for gas exchange.
