ThermoRegulation is the process by which living organisms maintain their internal body temperature within a certain range, despite external temperature changes. This is crucial for optimal functioning of enzymes and metabolic processes. Animals can be classified as endotherms, which generate heat internally, or ectotherms, which rely on external sources for heat. In humans, thermoregulation involves mechanisms like sweating to cool down and shivering to generate heat. The hypothalamus, a part of the brain, plays a key role in detecting temperature changes and triggering appropriate responses to maintain a stable internal environment.
