Which of the following is one way that the circulatory system maintain body temperature?
a. carrying heat around the body
b. speeding up the blood flow to generate heat
c. controlling the flow of blood to the skin
d. carrying nutrients and energy to cells

One way through which the circulatory system helps maintain body temperature is controlling the flow of blood to the skin (option C).

Explanation:

In situations of low ambient temperatures, one of the mechanisms to prevent the loss of body heat is the decrease in blood flow that reaches the skin.

In the presence of cold, body thermoreceptors send a signal to the nervous system, which arrives to the hypothalamic thermoregulation centers, activating body responses to maintain body temperature.

One of the responses to cold is peripheral vasoconstriction - closure of blood vessels in the skin - and the derivation of blood flow to vital organs. This produces the paleness that is observed in the skin when a person is exposed to cold.

Peripheral vasoconstriction is a way of controlling the blood flow to the skin to maintain body temperature.
