Which components make up the integumentary system?

• A. Skin, hair, nails, and sweat glands
• B. Bones and cartilage
• C. Muscles and nerves
• D. Lungs and airways

Answer: (A)

The integumentary system includes the skin and its accessory structures. The skin provides a protective barrier and helps regulate body temperature, while hair, nails, and sweat glands support those functions and contribute to sensation and protection. So, listing skin, hair, nails, and sweat glands matches this system. The other options point to different body systems: bones and cartilage are the skeletal system, muscles and nerves belong to the muscular and nervous systems, and lungs and airways are part of the respiratory system.
