The average internal temperature of human body is __________?
Correct answer: C. 37 oC
- A. 35 oC
- B. 36 oC
- C. 37 oC
- D. 38 oC
Explanation
The average internal temperature of a healthy human is approximately 37 °C, maintained by thermoregulatory mechanisms despite changes in the external environment. Students may choose 38 °C because fever can raise body temperature, but it is not the normal average.

About Thermoregulation
Thermoregulation maintains body temperature through negative feedback controlled mainly by the hypothalamus. It covers vasodilation and vasoconstriction, sweating, shivering, changes in metabolic heat production and behavioural responses, while distinguishing heat loss by radiation, conduction, convection and evaporation from temperature regulation itself.
