Question
Chapter 48, Problem 13TYK
Summary Introduction
To review:
The effect of increased air movement during shivering in an animal on heat conservation.
Introduction:
The shivering response occurs in animals when their core temperature falls below a set point. This action limits the loss of body heat due to convection. This is hence one of the ways adopted by the endotherm animals to conserve body heat.

If the blood temperature falls too low, this is also sensed by the brain and signals are sent to the cutaneous
arteries (those supplying the skin) to constrict them. Warm blood is then retained deeper in the body and
less heat is lost from the surface. If this is inadequate, the brain activates shivering. Each muscle tremor in
shivering releases heat energy and helps warm the body back toward its 98.6 degrees set point.
• This is an example of
a. a negative feedback loop
b. a positive feedback loop
Heat exchange with the environment depends on the surface area-to-volume ratio of the body. Assuming that the body shape of an animal is at least somewhat spherical, a
considerable decrease in body size would
the surface area-to-volume ratio, and the ability to exchange heat with the environment would
A. increase; increase
B. increase; stay about the same
C. increase; decrease
D. decrease; increase
E. decrease; stay about the same
Which of the following would increase the rate of heatexchange between an animal and its environment?(A) feathers or fur(B) vasoconstriction(C) wind blowing across the body surface(D) countercurrent heat exchanger
