The red gills of this common carp are visibly exposed as a result of a gill flap birth defect. A gill (/ ɡɪl / ⓘ) is a specialized respiratory organ that many aquatic animals use for aquatic gas exchange, i.e. to extract dissolved oxygen from water and to excrete carbon dioxide. Branchia (pl.: branchiae, from Ancient Greek βράγχια) is the zoologists ' academic name for gills. The ...
Gills extract oxygen from water and release carbon dioxide. Their structure maximizes surface area for efficient gas exchange through diffusion.
How Do Gills Work? | Function, Oxygen Uptake, & Fish - Britannica
Gills are specialized organs that allow many aquatic animals to extract dissolved oxygen from water and release carbon dioxide. They serve as the primary means of respiration for a vast array of organisms. This function is essential, as water contains significantly less oxygen than air, enabling diverse aquatic species to inhabit various watery environments across the globe. How Gills Work The ...
Everyone knows fish have gills that let them breathe underwater, but how exactly do they work? Learn the fascinating answer right here in this guide!
Gills allow aquatic and semi-aquatic animals to breathe by absorbing tiny particles of dissolved oxygen from water and excreting carbon dioxide as a byproduct of respiration. In most species, they are composed of numerous tiny, thin tissues or folded, branch-like structures. Their folded design helps increase their surface area and respire more efficiently.
