Which function is not associated with the integumentary system?

The integumentary system, which includes the skin, hair, nails, and associated glands, serves several critical functions that are integral to the body's overall health and homeostasis. One of the primary roles of this system is protection; it acts as a barrier against pathogens, UV radiation, and physical injuries. Additionally, the integumentary system contributes to absorption, such as through the skin's ability to absorb certain substances, including moisture and fat-soluble vitamins.

Another important function is communication, which occurs through sensory receptors in the skin. These receptors detect environmental changes, such as temperature, pressure, and pain, and relay that information to the brain, thereby playing a role in how the body interacts with its surroundings.

However, coordination is not a function typically associated with the integumentary system. Coordination refers more to the integrative processes managed by the nervous and endocrine systems, where they work together to regulate various bodily functions and responses. Therefore, the function of coordination is distinct from the primary roles of the integumentary system, making it the correct answer in this context.
