Warm-Blooded - English Definition & Meaning

Definition

'Warm-blooded' refers to animals that maintain a stable internal body temperature regardless of the surrounding environment. Think of mammals and birds that can regulate their body heat even in cold weather 🐦. This ability is also known as endothermy. Unlike 'cold-blooded' (ectothermic) animals, warm-blooded creatures expend energy to keep their temperature constant. Imagine a dog panting in the summer to cool down or shivering in the winter to generate heat 🐶. It is a defining characteristic of several classes of animals.

Etymology

'Warm-blooded' combines 'warm' with 'blooded,' referring to the warmth of the blood. As mentioned previously, 'warm' comes from the Old English 'wearm,' meaning 'warm.' The term has been used for centuries to differentiate between animals that regulate their own body temperature and those that rely on external sources of heat. It reflects a fundamental biological distinction. 🌡️
