Fish Anatomy

Functions of the Gill Gill Functions When water is passed over the gills, oxygen is absorbed and carbon dioxide and ammonium is exhaled. 75% of the ammonia excreted by the fish is through the gills. The gills also help the fish osmoregulate, (equalize body pressures). They are covered by a bony flap known as the operculum. Each gill consists of a bone arch with filaments extending at right angles to the arch. Lamellae are the tiny branches on the filaments. Healthy gills are bright red and do not stick together.
