How do gills function during respiration?
! Fish take oxygen from the water by swallowing water (H20) into their mouths, but they don't take down their throats instead they force the water through their gills where blood in the gills soaks up the oxygen from the water.
Do you need to have gills to breathe underwater?

Could humans evolve gills?
It is highly unlikely that humans could evolve gills, as this would require drastic and improbable genetic changes. Humans are adapted to breathe air, and developing functional gills would involve significant alterations to our respiratory and circulatory systems. Additionally, the evolution of such a complex trait would likely take millions of years, if it were possible at all.
