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
Although total liquid ventilation (TLV) with completely liquid-filled lungs can be beneficial, [9] the complex liquid-filled tube system required is a disadvantage compared to gas ventilation—the system must incorporate a membrane oxygenator, heater, and pumps to deliver to, and remove from the lungs tidal volume aliquots of conditioned perfluorocarbon (PFC).
6 Dissolved oxygen density of water and human oxygen requirements are limiting factor
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 ...
Humans did not evolve from either of the living species of chimpanzees (common chimpanzees and bonobos) or any other living species of apes. [174] Humans and chimpanzees did, however, evolve from a common ancestor. [175] [176] This most recent common ancestor of living humans and chimpanzees would have lived between 5 and 8 million years ago. [177]
This new printer was able to use live human cells without having to build an artificial scaffold first. [9] In 2009, Organovo used this novel technology to create the first commercially available bioprinter. [9] Soon after, Organovo's bioprinter was used to develop a biodegradable blood vessel, the first of its kind, without a cell scaffold. [9]
Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. [1] A machine called a ventilator provides the person air manually by moving air in and out of the lungs when an individual is unable to breathe on their own.
