Ectotherm - Wikipedia
https://en.wikipedia.org/wiki/EctothermWebAn ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat") is an organism in which internal physiological sources of heat are of relatively small or of quite negligible importance in controlling body temperature. Such organisms (for example frogs) rely on environmental heat sources, which permit them to operate at very economical …
Poikilotherm - Wikipedia
https://en.wikipedia.org/wiki/PoikilothermWebA poikilotherm (/ ˈ p ɔɪ k ə l ə ˌ θ ɜːr m, p ɔɪ ˈ k ɪ l ə ˌ θ ɜːr m /) is an animal whose internal temperature varies considerably. Poikilotherms have to survive and adapt to environmental stress. One of the most important stressors is temperature change, which can lead to alterations in membrane lipid order and can cause protein unfolding and denaturation at …
Thermoregulatie - Wikipedia
https://nl.wikipedia.org/wiki/ThermoregulatieWebThermoregulatie is het vermogen van een organisme om de lichaamstemperatuur te handhaven. Sommige organismen doen dit direct door zelf warmte te produceren of af te geven (warmbloedig).Andere organismen doen dit indirect door op te warmen in de zon, en af te koelen in de schaduw (koudbloedig).Ieder organisme heeft een ideale temperatuur, …
Homeothermy - Wikipedia
https://en.wikipedia.org/wiki/HomeothermyWebHomeothermy, homothermy or homoiothermy is thermoregulation that maintains a stable internal body temperature regardless of external influence. This internal body temperature is often, though not necessarily, higher than the immediate environment (from Greek ὅμοιος homoios "similar" and θέρμη thermē "heat"). Homeothermy is one of the three types of …

https://pt.wikipedia.org/wiki/PoiquilotermiaWebOs organismos designados vulgarmente como animais de "sangue frio", animais de temperatura variável, poiquilotérmicos, pecilotérmicos, ectotérmicos ou heterotérmicos são metazoários que não têm um mecanismo interno que regule a temperatura do seu corpo. Desta forma, ou o seu corpo está estável ou comportada permanece com temperatura …
Endothermic process - Wikipedia
https://en.wikipedia.org/wiki/Endothermic_processWebIn thermochemistry, an endothermic process (from Greek ἔνδον (endon) 'within', and θερμ-(therm) 'hot, warm') is any thermodynamic process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. Thus, an …

Koudbloedig - Wikipedia
https://nl.wikipedia.org/wiki/KoudbloedigWebEen koudbloedig organisme is een dier dat zelf geen eigen lichaamswarmte kan produceren, in tegenstelling tot een warmbloedig organisme. De regeling van de lichaamstemperatuur is afhankelijk van gedrag als het opzoeken van warmere of koelere plaatsen of door te zonnebaden. Bekende koudbloedige dieren zijn vissen, reptielen, …
