b. free fatty acids in spite of increased circulating catecholamines
, c. glucose/glycogen due to increased circulating catecholamines
d. glucose/glycogen in spite of increased circulating catecholamines
d
When muscle glycogen and blood glucose both start to run low during exercise
in the cold, the possible consequence is __________.
a. suppression of shivering
b. frostbite
c. enhanced skin vasoconstriction

Wet clothing and being in the cold river contributed to Jones' heat loss by what
thermal mechanism?
a. Convection.
b. Conduction.
c. Evaporation.
d. Radiation.
a
Propose a mechanism that accounts for how warming the skin can stop shivering
in patients with core body temperatures that would usually induce shivering,
__________.
a. because warming the skin causes the skin temperature receptors detect warm,
which tells the hypothalamus wrongly that the body is warm
