Study Notes

Thermoregulation

Thermoregulation is the process of regulating body temperature.
It's a crucial homeostatic system for all organisms, from large mammals to tiny bacteria.
Maintaining an optimal temperature is essential for survival.
Factors influencing temperature regulation include regulatory systems and organism size.
Regulating body temperature is one of the most important and obvious homeostatic systems.

Endotherms

Endotherms, or "warm-blooded" animals, regulate their temperature internally via internal physiological processes.
Birds and mammals (including humans) are examples of endotherms.

Ectotherms

Ectotherms, or "cold-blooded" animals, rely on external sources to regulate their body temperature.
Reptiles and amphibians are examples of ectotherms.
