Show transcript
Human body temperature needs to be kept within a small range, around 37°C, to maintain body functions and health.
Changes in the external environment can cause the internal body temperature to change.
When temperature decreases, responses (erection of hairs, vasoconstriction) help to return body temperature to normal.
When temperature increases, responses (sweating, vasodilation) help to return body temperature to normal.
