What is gills

Ray gills are usually lamellar or filamentous appendages , through which the blood circulates, and in which it is exposed to the action of the air contained in the water. In vertebrates they are appendages of the visceral arches on either side of the neck. In invertebrates they occupy various situations.

Science: botany The radiating, gill -shaped plates forming the under surface of a mushroom. Science: zoology The fleshy flap that hangs below the beak of a fowl; a wattle. The flesh under or about the chin. One of the combs of closely ranged steel pins which divide the ribbons of flax fibre or wool into fewer parallel filaments.
