Humans inhabit hot climates, both dry and humid, and have done so for millions of years. Selective use of clothing and technological inventions such as air conditioning allows humans to live in hot climates. One example is the Chaamba, who live in the Sahara Desert. They wear clothing that traps air in between skin and the clothes, preventing ...
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
Her brain was so cold when the heart stopped that the brain cells needed very little oxygen, so the brain could survive for quite a prolonged time." [ 6 ] Gilbert also noted that therapeutic hypothermia , a method used to save those in circulatory arrest by lowering their body temperature, has become more frequent at Norwegian hospitals after ...
At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
Cold-blooded animals are often limited by external temperatures, which can affect their ability to hunt, escape predators, and carry out other essential activities. Homeothermy could have provided a selective advantage by allowing animals to be active for longer periods of time, increasing their chances of survival.
A company called Tomorrow Biostasis is focusing on human cryopreservation in the hopes it can eventually reverse death. The new Berlin startup has already preserved the bodies of about 10 deceased ...
Cold-blooded is an informal term for one or more of a group of characteristics that determine an animal's thermophysiology. These include: Ectothermy, controlling body temperature through external processes, such as by basking in the sun; Poikilothermy, the ability of an organism to function over a wide internal temperature range
