Gill arches in fish provide structural support for the gills and contain blood vessels that aid in oxygen exchange. They also help regulate the flow of water over the gills to maximize oxygen uptake and remove carbon dioxide. Additionally, gill arches play a role in vocalization and feeding in some species of fish.
The gill filaments are the hair-like structures on the gills which absorb the oxygen from the lamallae. The gill arch, on the other hand, acts as a form of muscle which holds the structures of the gills together. ~Sincerely, A Smarty pants :)
To incease the surface area of the gills so more oxygen can be diffused from the water the fish swims in into there bloodstream where the oxygen can be carried the fish's cells for cellular respiration
The gill rakers on fish keep food particles from moving out from in between the gill arches. For filter feeding fish and some suspension feeding fish, the gill rakers function is to trap the food.
