What is the difference between human and fish in terms of respiration?

Question

difference of human lungs and fish gills.

Answer 1

in humans respiration takes place in lungs but in fish it takes place in gils.

Answer 2

Humans take in air, and the capillaries around the alveoli in the lungs exchange CO2 for oxygen so the body can perform cellular respiration. And not die.

I believe fish take in water through their gills, operculate to extract the oxygen from the water, then just breath in the oxygen.

Look at the site I posted.

Answer 3

Hmmm confusing term really...respiration refers to the metabolism of a creature involving the production of energy. The difference however in the respiratory systems is that human lungs remove oxygen and return carbon dioxide to air and fish gills do it with water. Fish suck water in through their mouths and then force it through the filaments of their gills where gas exchange takes place as the water passes out of the slits that we see on the side of them. In humans we actively decrease the pressure of our lungs by diaphragm and intercostal muscle contractions, to cause air to rush in and gas exchange occurs across the alveoli membranes when they are aerated.
