In several unrelated lines of fishes, the bladder has become specialized as a lung or, at least, as a highly vascularized accessory breathing organ. The air enters the nasal cavity and makes it's way down the trachea . It breathes by means of gills borne in a series of gill-pouches on either lateral side of the pharynx. Ultimately, the gills release the carbon dioxide in water passing through them. Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills.The 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.

Immediately with the entry of water, the pharyngeal and the buccal cavities contract and exert pressure to the contained water. Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. Gas bladders differ in lungs in two ways 1. Other senses (touch, pain, and special senses).

Cells in your trachea and bronchial tubes make mucus that keeps air passages moist and helps keep things like dust, bacteria and viruses, and allergy-causing things out of your lungs. There are five pairs of gill-pouches, each of which communicate with the pharyngeal cavity by a large internal branchial aperture and opens to the outside by exterior gill-slits (Fig. Respiratory System.
