Question

To lose heat,flushing is generally accompanied by
A) activation of the eccrine glands.
B) secretion of sebum.
C) contraction of the arrector pili muscles.
D) constriction of the cutaneous blood vessels.

Accepted Answer

Activation of the eccrine glands is the main mechanism for losing heat during flushing. Flushing leads to dilation of blood vessels, bringing warm blood to the skin's surface. Eccrine glands produce sweat, which evaporates and cools the skin, allowing excess heat to be released. Additionally, flushing does not necessarily involve sebum secretion or contraction of the arrector pili muscles, and constriction of cutaneous blood vessels would actually impede heat loss.
