lämpimäveriset

Lämpimäveriset is a Finnish term that translates to "warm-blooded" in English. It is most commonly used in the context of animal physiology, referring to endothermic animals, which are capable of generating and regulating their own body heat internally. This ability allows them to maintain a stable internal body temperature regardless of the external environment, a characteristic shared by mammals and birds. This physiological trait distinguishes them from ectothermic or "cold-blooded" animals, whose body temperature is largely dependent on external sources.

The term "lämpimäveriset" is also sometimes used metaphorically in Finnish to describe someone who is passionate, energetic, or enthusiastic. In this figurative sense, it implies a lively and vigorous disposition. However, its primary and scientific meaning relates to the biological classification of animals based on their thermoregulation. The ability to maintain a constant internal temperature is crucial for many biological processes, allowing warm-blooded animals to remain active in a wide range of environmental conditions, from cold climates to extreme heat. This metabolic capability is a significant evolutionary adaptation.
