How is the fish gills adapted to gas exchange

Fish gills are organs that allow fish to breathe underwater.

WebMost fish exchange gases using gills on either side of the pharynx (throat), forming the splanchnocranium, the portion of the skeleton where the cartilage of the cranium converges into the cartilage of the pharynx and its associated parts. [2] Gills are tissues which consist of threadlike structures called filaments. WebFish and many other aquatic organisms have evolved gills to take up the dissolved oxygen from water ( Figure 20.4 ). Gills are thin tissue filaments that are highly branched and folded. When water passes over the gills, the dissolved oxygen in water rapidly diffuses across the gills into the bloodstream.
