Which of the following is NOT one of the six skin functions?

Sensation
Protection
Digestion
Excretion

The correct answer is: Sensation

The correct answer is "C. Digestion" because digestion is not a function of the skin. The skin's six primary functions are protection, sensation, heat regulation, excretion, secretion, and absorption. Digestion is a function of the digestive system, not the skin.
