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.
