Question: 1 / 490

Which function does NOT relate to the integumentary system?

Regulating body temperature

Providing support for bones

The integumentary system primarily consists of the skin, hair, nails, and associated glands, and it plays critical roles in various physiological functions. One of those functions includes regulating body temperature through mechanisms such as sweating and altering blood flow to the skin. It also covers and protects the body's surfaces from external factors, like pathogens and environmental hazards, serving as a barrier. Additionally, it facilitates the detection of sensations like touch, pressure, and pain through specialized nerve endings present in the skin.

Providing support for bones, however, is primarily a function of the skeletal system. The skeletal system consists of bones and cartilage, which provide structure, protect vital organs, and anchor muscles. This functional distinction highlights that the integumentary system does not serve to directly support bone structure or functions, making this choice the correct answer in the context of the question.
