How do fish breathe using gills? In this video Science Steve and Lauren demonstrate fish gills and explain how fish obtain oxygen from the water through the gills.
3D animation explaining how fish use their gills to respirate, and how the counter-current approach to optimise blood oxygenation gets established.
This video explains how gas exchange occurs through the gills due to the large surface area, the concentration gradient, the moist surface and the thin membr...
Discover how fish breathe underwater using gills. This video explains the unique process that allows fish to extract oxygen from water.
This is how to cut and gill a fish.
How do fish use gills to breathe? Explore the science of gills, and how they make fish some of the most efficient breathers on Earth:
2 Ιαν 2023 · Fish gills are crucial respiratory organs that enable fish to breathe underwater by extracting oxygen dissolved in water and eliminating carbon dioxide from their bodies. Typically situated on each side of the fish’s head, these gills are shielded by a bony plate known as the operculum.
