  2. Fish gill - Wikipedia

    en.wikipedia.org/wiki/Fish_gill

    Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments. These filaments have many functions including ...

  3. Gill - Wikipedia

    en.wikipedia.org/wiki/Gill

    A current of water is maintained through the gills for gas exchange, and food particles are filtered out at the same time. These may be trapped in mucus and moved to the mouth by the beating of cilia. [16] Respiration in the echinoderms (such as starfish and sea urchins) is carried out using a very primitive version of gills called papulae.

  4. Osteichthyes - Wikipedia

    en.wikipedia.org/wiki/Osteichthyes

    All bony fish possess gills. For the majority this is their sole or main means of respiration. Lungfish and other osteichthyan species are capable of respiration through lungs or vascularized swim bladders. Other species can respire through their skin, intestines, and/or stomach. [18]

  5. Fish physiology - Wikipedia

    en.wikipedia.org/wiki/Fish_physiology

    The gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange. [10] When a fish breathes, it draws in a mouthful of water at regular intervals. Then it draws the sides of its throat together, forcing the water through the gill openings, so that it passes over the gills to the outside.

  6. Aquatic respiration - Wikipedia

    en.wikipedia.org/wiki/Aquatic_respiration

    Sea slugs respire through a gill (or ctenidium). Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.

  9. Hypoxia in fish - Wikipedia

    en.wikipedia.org/wiki/Hypoxia_in_fish

    Gill remodelling happens in only a few species of fish, and it involves the buildup or removal of an inter-lamellar cell mass (ILCM). As a response to hypoxia, some fish are able to remodel their gills to increase respiratory surface area, with some species such as goldfish doubling their lamellar surface areas in as little as 8 hours.
