Answer

Brief Explanations:

The integumentary system includes the skin which has nerve - endings that can sense stimuli like heat. When Henry touched the hot plate, nerve endings in the skin detected the heat and sent signals to the body to move the finger away as a protective response. Oil in the skin is mainly for lubrication and protection against microorganisms, hair standing up is related to the fight - or - flight response in some cases and not the main response to heat here, and nails do not absorb heat and move the finger away.

Answer:

Nerve endings in the skin responded to the heat.
