WebHowever, fish can recruit a hypobranchial pump for active jaw occlusion during hypoxia, using feeding muscles innervated by anterior spinal nerves. This same pump is used to ventilate the air-breathing organ in air-breathing fishes. Some reptiles retain a buccal force pump for use during hypoxia or exercise. WebHow fish breathe. Unlike land animals, which have lungs to take in oxygen from the air, fish have gills to breathe in the oxygen contained in water. This process of breathing begins when a fish gulps water through its mouth. The water enters the mouth and passes through the feathery filaments of the fish’s gills, which are rich in blood ...

WebMany air-breathing fishes have evolved an ability to gulp air and store it in well-vascularized internal organs which can be a true lung, a modified swimbladder, diverticula of the buccal, opercular or pharyngeal cavities, or the gut (Graham, 1997). These organs enable them to breathe air not only when exposed to air but also when in water. WebThe primary respiratory organs of vertebrates are gills and lungs, although the skin is sometimes used ... • air is added to the swim bladder to maintain its volume as fish dive and removed as the fish surfaces • gas glands may be associated with a countercurrent rete mirabile, which affects partial pressure and flow of oxygen into and out ...
