Using the extremes of
temperature that occur in a day’s skiing, this program shows the range of
mechanisms through which the human body maintains a steady internal
temperature and protects its vital organs: shivering, hair erection, and
rerouting of blood supplies to conserve heat; increased blood flow to the
body surface, sweating, and panting to lose heat. (26 minutes)
