WebGills 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. WebCapillaries are the site at which exchange of oxygen, carbon dioxide and nutrients takes place. The structure of capillaries makes them very well suited for this function. As capillaries are only one cell thick and have very thin permeable walls this means that substances can diffuse out of them very easily.
