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
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
Triton, "the world's first artificial gills technology" is a Swedish and Korean organization that claims they have created artificial gills for humans. [1] Released as an Indiegogo project on March 14, 2016, this technology claims to allow divers to spend 45 minutes underwater at depths of less than 15 feet.
Gill hyperplasia is a medical condition consisting of the inflammation, hyperplasia, or hypertrophy of gill tissue, caused by disease, poor water quality, or injury of the gills. Gill function is often impaired, causing significant oxidative stress. [1] Anabantiformes endure hyperplasia better than other species due to the possession of a ...
The free gills are white, as is the spore print. The oval spores measure 9–13 by 6.5–9 μm ; they do not turn blue with the application of iodine . [ 29 ] The stipe is white, 5–20 cm (2–8 in) high [ 30 ] by 1–2 cm ( 1 ⁄ 2 –1 in) wide, and has the slightly brittle, fibrous texture typical of many large mushrooms.
Pharyngeal clefts resembling gill slits are transiently present during the embryonic stages of tetrapod development. The presence of pharyngeal arches and clefts in the neck of the developing human embryo famously led Ernst Haeckel to postulate that " ontogeny recapitulates phylogeny "; this hypothesis, while false, contains elements of truth ...
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.
The nerve of the arch itself runs along the cranial side of the arch and is called post-trematic nerve of the arch. Each arch also receives a branch from the nerve of the succeeding arch called the pre-trematic nerve which runs along the caudal border of the arch. In human embryo, a double innervation is seen only in the first pharyngeal arch.
