Which statement about the gas exchange system in fish is correct?

WebYou would like to examine the effects of reversing the flow of water over the gill filaments of a perch (a medium-sized bony fish). To do so, you strap the fish into a water-filled chamber, treat it with a drug that temporarily paralyzes the mouth and opercular wall muscles, and use a pump to move a stream of water forward over the gills into the oral cavity.

Oxygen intake for respiration, also carbon dioxide and, generally, ammonia elimination takes place across gas-exchange surfaces, usually the gills in fish. Water flows across gills, separated by the pharyngeal gill clefts, and supported by gill arches, and which possess highly folded surfaces covered by a very thin epithelium. billy mitchell airport weatherWebOct 22, 2024 · When fish ventilate, water first enters the mouth where it is diverted towards two pairs of gills that sit either side of the fish. The water passes through a set of gills and then flows out of the fish via the operculum. When the fish inhales the operculum initially stays shut so that water can flow in their mouth (or buccal cavity). When the ... cynics ht4216

"WebOct 25, 2024 · This involves countercurrent exchange to keep the gaseous substances flowing. This results in a supported breathing mechanism in the animals. When an organism like fish draws the water in through the mouth, it forcefully passes out of the gills moving past the gill openings. This process helps in the exchange of oxygen in fish species.

Air breathing fish can be divided into obligate air breathers and facultative air breathers. Obligate air breathers, such as the African lungfish, are obligated to breathe air periodically or they suffocate. Facultative air breathers, such as the catfish Hypostomus plecostomus, only breathe air if they need to and can otherwise rely on their gills for oxygen. Most air breathing fish are facultative air breathers that avoid the energetic cost of rising to the surface and the fitness cos… WebThe gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange. [5] When a fish breathes, it draws in a mouthful of water at regular intervals.
