"WebAdaptations of the Alveoli. The lungs are the gas exchange surface in humans and so are adapted to maximise the exchange of gas by diffusion. Inside the lungs there are many rounded alveolar sacs which give a very large surface area to volume ratio. These alveoli are highly specialised structures. They (and the capillaries around them) have ... " - How are fish gills adapted for diffusion

(Open Access) Gill Structure of the Yellowtail and Frogfish (1983)

WebThe folded surfaces of the gills provide a large surface area to ensure that fish obtain sufficient oxygen. Diffusion is a process in which material travels from regions of high concentration to low concentration until equilibrium is reached. In this case, blood with a low concentration of oxygen molecules circulates through the gills. WebFish possess several gills located between their mouth cavity (buccal cavity). Gills of fishes consist of several gill arches on either side. From each gill arch extend two rows of gill …
