This internal body temperature is often, though not necessarily, higher than the immediate environment [2] (from Greek ὅμοιος homoios "similar" and θέρμη thermē "heat"). Homeothermy is one of the 3 types of thermoregulation in warm-blooded animal species. Homeothermy's opposite is poikilothermy. A poikilotherm is an organism that ...
Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. Warm-blooded is an informal term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic processes
Heat loss is a major threat to smaller creatures, as they have a larger ratio of surface area to volume. Small warm-blooded animals have insulation in the form of fur or feathers. Aquatic warm-blooded animals, such as seals, generally have deep layers of blubber under the skin and any pelage (fur) that they might have; both contribute to their ...
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
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]
It stayed cool for at least a good two hours before I put some more ice water on it. Even just a little bit of water was able to make it nice and cold again and extremely helpful in the 104° weather.
The cold weather hitting much of the East Coast has the ability to be dangerous or deadly because of unsafe exposure to elements. This week's winter storms are tracking to the south, and cold air will likely be present as far south as Georgia, said Jon Palmer, a meteorologist with the National Weather Service in Gray, Maine.
The safest way to do this is to use a heat sink such as a jug filled with hot water or stones warmed in the sun. These materials slowly release heat during the night, keeping temperatures beneath ...
