Heat loss occurs with which of the following?
 
  a. vasodilation c. piloerection
  b. vasoconstriction d. muscle shivering

Question 2

The rate of energy use in the body needed to maintain essential activities is known as
 
  a. baseline values c. hemodynamic regulation
  b. basal metabolic rate d. thermoregulation

Answer to Question 1

A
Vasodilation is the widening of blood vessels to inhibit heat production. Vasoconstriction will lead to the production of heat by narrowing the blood vessels. Heat is also produced by muscle shivering. Piloerection is the term used to describe the body hairs standing on end, often seen in a person who is cold or shivering.

Answer to Question 2

B
Basal metabolic rate is the rate of energy use in the body needed to maintain essential activities. Thermoregulation is the body's physiological function of heat regulation to maintain a constant internal body temperature. Baseline values establish the norm against which subsequent measurements can be compared. Hemodynamic regulation is the physiological function of blood circulating to maintain an appropriate environment in tissue fluids.
