How do fish gills function in respiration?

Answer 1

to protect the gills

Answer 2

the ability to take the oxygen molecule out of the H2O molecule

*another part transports the oxygen
All gills are organs that enable an aquatic animal to exchange metabolite gasses (O2 and CO2) with the environment to support the process of respiration - to "breath"

-------------------------------------------------------------------------

They work like your lungs. Lungs extract oxygen from the air just as gills extract oxygen from water.
Fishes use gills for breathing underwater and to obtain oxygen.

The function of the gill system is so that fish and other sea creatures are able to breathe under water. To do this they have to continually swim so that the oxygen they require for survival is pushed through the gills and absorbed into the body to where it is needed. Fish cannot sleep unless in a tide because the oxygen will stop getting into the body and the fish will suffocate. Basically the function of the gill system is to help fish and other sea mammals be able to breathe.

Answer 3

The gills of the fish help it to breath. If the gills are open, the fish id alive, but if the gills are closed, this means that it can no longer breath, and is dead.

Answer 4

They take in the water and remove the dissolve O2 in it.

Answer 5

breathing

Just like the purpose of lungs in land animals.

Answer 6

Fish use gills to breathe under water. A fish intakes water from its mouth, oxygen is absorbed through gills and water is thrown out.

Answer 7

TO BREATH... idiot

Answer 8

They are used to help fish breathe.
