What is a complex function of the integumentary system?

Developing immunities
Serving as a protective covering and helping regulate the body's temperature
Coordinating body systems
Circulating blood

The correct answer is: Serving as a protective covering and helping regulate the body's temperature

The integumentary system serves as a protective covering for the body and helps regulate body temperature through sweat production and blood flow. It is not responsible for developing immunities, coordinating body systems, or circulating blood. These functions are primarily carried out by the immune system, nervous system, and cardiovascular system, respectively.
