The fish gill is arguably the most physiologically diversified and anatomically complex vertebrate organ. Bony fish have eight gill arches, four on each side of the mouth cavity. Each arch bears numerous paired filaments and many thin respiratory lamellae, thereby greatly increasing the respiratory surface area. A variety of cells including osmoregulatory ionocytes (chloride cells), protective mucous cells, and oxygen-sensitive chemoreceptor cells are also distributed throughout the gill and serve a variety of homeostatic functions. As many as three distinct vascular pathways perfuse the gill tissue and support these activities.
