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

This action, rather than muscular peristalsis, is responsible for the movement of food through the gastropod digestive tract. [1] Two diverticular glands open into the stomach, and secrete enzymes that help to break down the food. In the more primitive species, these glands may also absorb the food particles directly and digest them ...
The external gill rami are lined with filaments (fimbriae) to increase surface area for gas exchange. [15] Four-gill slits lined with gill rakers are hidden underneath the external gills, which prevent food from entering and allow particles to filter through. Axolotls have barely visible vestigial teeth, which develop during metamorphosis.

A Business Insider video about preauricular sinus points out that evolutionary biologist Neil Shubin suspects "these holes could be evolutionary remnant of fish gills."
The gill arches of bony fish typically have no septum, so that the gills alone project from the arch, supported by individual gill rays. Some species retain gill rakers . Though all but the most primitive bony fish lack a spiracle, the pseudobranch associated with it often remains, being located at the base of the operculum.
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
