Answer 1

Your body temperature isn’t uniform at all, that’s why in the past a thermometer without a logic board needed to be inserted into the rectum, or under the tongue, to get the *core temp*. It’s that core temp that needs to be maintained in a specific range, and the rest of your body varies wildly. Beyond that, blood flow and dilation/constriction of blood vessels which determines blood flow, are the main mechanisms to modify body temp, along with sweating.
