Artificial gills are hypothetical devices to allow a human to be able to take in oxygen from surrounding water. This is speculative technology that has not yet been demonstrated. Natural gills work because most animals with gills are thermoconformers (cold-blooded), so they need much less oxygen than a thermoregulator (warm
In most other gastropods, the right gill has been lost. In groups such as the turban shells the gill still retains its primitive bipectinate form, and in these animals, the water current is oblique, entering the mantle cavity on the left side of the head, flowing over the gill, and then being flushed out on the right side. The anus is also on ...
Artificial gills may refer to: Imitation gills put into stuffed fish for the sake of appearance in taxidermy; An inaccurate term for liquid breathing sets; Artificial gills (human), which extract oxygen from water to supply a human diver
Humans still have tails when we’re developing in the womb as embryos; this wee appendage is a hand-me-down from the tailed ancestor of all vertebrates and includes 10 to 12 vertebrae.
Destroying angels are characterized by having gills and white stalks. The cap can be pure white, or white at the edge and yellowish, pinkish, or tan at the center. It has a partial veil, or ring circling the upper stalk, and the gills are "free", not attached to the stalk.
Cutaneous respiration, or cutaneous gas exchange (sometimes called skin breathing), [1] is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs. Cutaneous respiration may be the sole method of gas exchange, or may accompany other forms, such as ventilation.
There is a birth defect of the ear that is visible and relatively common around the world. It is called preauricular sinus which, according to the U.S. National Institutes of Health, or NIH ...
The gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange. [5] When a fish breathes, it draws in a mouthful of water at regular intervals. Then it draws the sides of its throat together, forcing the water through the gill openings, so it passes over the gills to the outside.
