Which statement regarding "heat loss" is true?
A) Muscle activity does not generate heat.
B) Shivering in a cold environment results in higher levels of heat loss.
C) When skeletal muscles are contracting at peak levels, body temperature drops.
D) Heat loss is reduced when blood flow to the skin increases.
E) Muscle contractions play an important role in the maintenance of normal body temperature.

Question

Quizplus · Accepted Answer

Muscle contractions play an important role in the maintenance of normal body temperature. This is achieved through the heat generated by muscle activity. The more active the muscles, the more heat is produced, which helps to maintain a stable core body temperature. Shivering, which is a muscle contraction, is also a physiological response to cold temperatures that helps to generate heat and increase body temperature. When skeletal muscles are contracting at peak levels, body temperature may actually rise, rather than drop. Heat loss is increased when blood flow to the skin increases, as this allows for greater heat transfer from the body to the environment.
