Quizplus · Accepted Answer

Gill arches are large, bony structures in fish that support the gill filaments, which are responsible for gas exchange. The gill filaments are attached to the gill arches, which provide support and protection for the delicate structure of the gills. Gill flaps are soft, fleshy structures that help to control water flow over the gills, while gill lamellae are the thin, flat structures that make up the surface area of the gills. Gill rakers are small projections in the pharynx that help to filter food particles from the water, and gill slits are the openings on the sides of the fish's head through which water passes over the gills.
