Thermoregulation

Thermoregulation

The process of maintaining internal temperature through negative feedback mechanisms.

Endotherm

An animal that regulates its temperature through internal mechanisms by producing its own heat.

Ectotherm

An animal that regulates its temperature by relying on external heat sources from the environment.

Poikilotherms

Animals that can survive at a wide range of temperatures and allow their body temperature to fluctuate.

Homeotherms

Animals that require a specific and consistent range of temperature to survive.

Thermoreceptors

Sensors in the skin that detect heat.

Hypothalamus

The part of the brain responsible for regulating body temperature.

Vasoconstriction

The narrowing of blood vessels to reduce heat loss.

Vasodilation

The widening of blood vessels to release heat.

Torpor

A state of reduced metabolic activity and body temperature.

Thermal Acclimatization

Seasonal adjustments made by animals to survive changes in weather conditions.
