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 proper functioning, as enzymes and other biochemical processes operate optimally at specific temperatures. Animals can be classified as endotherms, which generate heat internally (like mammals and birds), or ectotherms, which rely on external sources of heat (like reptiles and amphibians). Various mechanisms are involved in thermoregulation, including sweating, shivering, and altering blood flow to the skin. In humans, for example, sweating helps cool the body when it overheats, while shivering generates heat when it is cold. The hypothalamus, a part of the brain, plays a key role in regulating these processes by detecting temperature changes
