Endotherms

Organisms that regulate their body temperature through internal metabolic processes, often referred to as warm-blooded organisms.

Shivering

A rapid, involuntary contraction and relaxation of muscles that produces heat in response to cold.

Brown Fat

A type of body fat that is activated when cold, burning calories to generate heat and help maintain body temperature, containing more mitochondria than white fat.
