Dogfish gill. Light micrograph of a section through a gill lamella from a lesser spotted dogfish (Scyliorhinus canicula). Running across centre is a brachial artery. The wavy parallel lines are the secondary lamellae of the gills, which are very thin and consist of two epidermal layers enclosing a layer of capillaries from the brachial arteries. These secondary lamellae increase the surface area and shorten the diffusion path, which speeds up the absorption of oxygen and expulsion of carbon dioxide through the gills. Fish use gills to obtain oxygen from the surrounding water. Magnification: x14 when printed at 10 centimetres across.
