Pete decided to go camping during December in Canada all by himself. Half way to the camp site his car ran out of gas so he decided to try walking. In what way will his body try to protect itself from the cold?
Explanation
Answer: D - Vasoconstriction, piloerection, and sympathetic stimulation are all ways in which the body tries to protect itself from the cold. Piloerection is the body attempting to produce heat by shivering. When the body becomes too hot it attempts to eliminate body heat through five mechanisms: vasodilation, perspiration, decreased heat production, increased cardiac output, and increased respiratory rate.
