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
A dust storm traveling from the Sahara Desert over the Atlantic Ocean. Dust in Earth's atmosphere comes from both natural and anthropogenic causes. [1] The process of which dust enters Earth's atmosphere naturally can be attributed to the Aeolian process where winds erode Earth's surface and consequently carry particles from the ground into the atmosphere via suspension, whereas anthropogenic ...
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
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 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.
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 ...
Humans have many wonderful qualities, but we lack something that’s a common feature among most animals with backbones: a tail. Exactly why that is has been something of a mystery.
The Root effect is a physiological phenomenon that occurs in fish hemoglobin, named after its discoverer R. W. Root.It is the phenomenon where an increased proton or carbon dioxide concentration (lower pH) lowers hemoglobin's affinity and carrying capacity for oxygen.
