1. the ability of an organism to maintain a relatively constant body temperature independent of environmental temperature; warm-bloodedness.
Usage: also spelled homiothermy; technical/scientific term; contrasts with poikilothermy (cold-bloodedness)

Examples

• Mammals and birds rely on homoiothermy to survive in cold climates.
• The homoiothermy of humans allows us to maintain a stable body temperature of about 98.6°F.
• Unlike reptiles, animals with homoiothermy can remain active in winter.
• Homoiothermy requires significant energy expenditure to regulate internal heat.
• Scientists study homoiothermy to understand how different species adapt to their environments.
