What is the primary function of the gills?

What is the primary function of the gills?

The gill filaments in fish have functions like lungs in people: it’s the organ responsible for absorbing oxygen and expelling carbon dioxide. The gills also regulate levels of mineral ions and the pH of the blood, as well as being the primary site of nitrogenous waste excretion, in the form of ammonia.

Why do fish need gills to breathe?

Unlike land animals, which have lungs to take in oxygen from the air, fish have gills to breathe in the oxygen contained in water. The fish’s heart pumps the blood to distribute the oxygen throughout the body. At the same time, waste carbon dioxide in the blood passes out through the gills into the water.

What is the job of gills?

“Their primary purpose is to exchange gases, take oxygen in and release carbon dioxide out of the fish.” Both lungs and gills have a bed of very small blood vessels with thin walls that the gases can easily travel across. But gills have a much harder job than lungs, Malison says.

How do fish breathe with gills?

Gills are full of blood vessels. When the water moves through the gills, the dissolved oxygen from the water passes through the thin walls of gills and blood vessels, and enters the blood. Apart from this, the waste carbon dioxide present in the blood passes into the water, thus helping fish to breathe underwater.
