Fish Gills Basic Biology

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.

Web28 de dez. de 2024 · Water is taken through the mouth and is forced over the gills and out through an opening on each side. The gills of a fish are efficient at gas exchange as they have a large surface area with each lamellae. They also have a short diffusion pathway which further increases the gas exchange efficiency. WebThe gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Water taken in continuously through the mouth passes backward between the gill bars and over the gill filaments, where the exchange of gases takes place.
