Question

Which of these processes increase(s) heat loss from the body? select one:
a. dilation of dermal arterioles
b. constriction of dermal arterioles
c. increased sweating
d. both a and c
e. both b and c?

Answer 1

answer is D. both a and c

Answer 2

The processes that increase heat loss from the body are dilation of dermal arterioles and increased sweating (Options a and c).

• The human body has developed several adaptations in order to eliminate excess heat.

• An arteriole is a small blood vessel that branches out from an artery and carries blood toward smaller capillaries.

• The dermal arterioles can dissipate the excess of heat through the skin and into the environment.

• Moreover, the body also secretes a liquid from the sweat glands (i.e., sweat) that helps the body stay cooler when evaporates from the skin's surface.

In conclusion, the processes that increase heat loss from the body are dilation of dermal arterioles and increased sweating (Options a and c).
