What is the primary function of the integumentary system?

• A. To protect and maintain homeostasis
• B. To digest food
• C. To pump blood
• D. To regulate hormones

Answer: (A)

The main function of the integumentary system is to protect the body and help maintain homeostasis. The skin acts as a strong barrier against physical injury, pathogens, and water loss, while also regulating body temperature through sweating and adjusting blood flow to the skin. This combination keeps the internal environment stable and safe. Digestion is handled by the digestive system, pumping blood by the circulatory system, and hormone regulation by the endocrine system, so those options don’t describe the skin’s primary role.
