Final answer:
The primary factors that influence thermal regulation of the human body are metabolism, radiation, evaporation, and convection.The correct option is B.
Step-by-step explanation:
The primary factors that influence thermal regulation of the human body are metabolism, radiation, evaporation, and convection.
Metabolism is the process by which the body converts food and oxygen into energy. It generates heat as a byproduct, helping to maintain body temperature.
Radiation is the transfer of heat through electromagnetic waves. It occurs when heat is radiated from the body to the environment
Evaporation occurs when sweat on the skin evaporates, taking heat with it and cooling the body. Convection is the transfer of heat to the surrounding air or water.The correct option is B.
