Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs and out of the body. It takes place in the alveoli. The walls of the alveoli are surrounded by a network of blood capillaries. In fact the alveoli walls share a membrane with the capillaries which allows for oxygen to diffuse through the alveoli wall.

Fish use specialised surfaces called gills to carry out gas exchange. Gills are highly folded, giving them a large surface area and maximising the efficiency of gas exchange. The gill filaments have many protrusions called gill lamellae. One of the ways in which gas exchange is carried out efficiently is by the countercurrent flow principle.

It allows maximum oxygen to be absorbed by the blood from the water, by maintaining the concentration gradient the whole way through the gills. This means fish can get enough oxygen without having to push large amounts of water through their gills. Because water is viscous, this would require a lot of energy, so the.
