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.
