Regulation of Body Temperature

APBIO-21TS72

As the water evaporates from the skin of a swimmer who has just left a pool, the swimmer begins to shiver and goosebumps form on his skin. As the blood vessels under his skin move more internally, the goosebumps that form and the shivering are reactions to counteract the lowering of body temperature.

After the swimmer has dried off, the shivering stops, and his body temperature returns to normal.

Which of the following is the MOST likely explanation?

A

Product inhibition.

B

Disequilibrium.

C

A negative feedback mechanism.

D

A positive feedback mechanism.
