What is one function of the integumentary system?

The integumentary system plays a crucial role in protecting the body from dehydration, which is one of its primary functions. This system includes the skin, hair, nails, and associated glands, forming a barrier that prevents excessive water loss from internal body tissues. By maintaining moisture levels within the body, the integumentary system helps to ensure proper physiological functions and protects against external environmental factors. This protective function is vital for overall health, as dehydration can lead to numerous health problems, including impaired organ function and the inability to regulate body temperature effectively.

In contrast, the other options relate to different body systems: muscle contractions are a function of the muscular system, food and waste storage are functions associated with the digestive and excretory systems, and blood cell production is primarily carried out by the hematopoietic system within the bone marrow. Each system has its specialized functions, contributing to the overall homeostasis of the body.
