 Match the following mechanisms (Column I) with their correct example (Column II).

Column I	Column II
A. Heat-generating and heat-retaining mechanisms	i. increased metabolic rate (thyroid hormones, sympathetic nervous system)
B. Heat-dissipating mechanisms	ii. vasodilation of blood vessels of the skin (decreased sympathetic tone)
	iii. increased activity of sympathetic cholinergic fibers to sweat glands.
	iv. shivering
	v. vasoconstriction of blood vessels of the skin (increased sympathetic tone)
