yes they swallow water and expel the used water out their gills.
The openings in the throat region of a fish that lead to the gill chamber are called gill slits. These slits allow water to flow over the gills so that oxygen can be absorbed and carbon dioxide can be released.
That is a hard but flexible cover which, in bony fish, forms the outer wall of the gill chamber. It protects the gills and also plays a major role in the pumping mechanism that regulates the continuous flow of water over them.
First, dissolved oxygen in the water is absorbed by the creature and then it flows through the gill chambers. And the waste products flow through the gill chambers and it will be passed out through the body.
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.
Bony fish have many gill filaments because they use them to breathe. They are also used to transfer things like water and ions.

In most fish species, the number of times the mouth opens and closes is unrelated to the number of times the gill covers move. The two movements serve different functions: the mouth is used for feeding and respiration, while the gill covers are specifically involved in respiration. These movements are controlled by different mechanisms in the fish.
It is a gill chamber.

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.
Tilapia have four pairs of gills, totaling eight gill arches in their gill chamber. Each gill arch supports numerous gill filaments, which are responsible for gas exchange. This structure allows tilapia to efficiently extract oxygen from water as they breathe.
Fish take in water through their mouth. The water is passed over the gills, where oxygen is extracted, and the water then passes out back into the water by the external gill coverings.
a) Goldfish (all fish) breathe through their gills b) All fish (Including Goldfish) suck water in through their mouth and pass it through their gill filament's.
It is used to cover the gill on the fish.
