Which system protects the body from germs and helps regulate heat and moisture, containing epidermis and dermis?

• A. Skin System
• B. Nervous System
• C. Urinary System
• D. Musculoskeletal System

Answer: (A)

The skin, or integumentary system, is the body’s frontline defense against germs and also helps regulate heat and moisture. It has two main layers: the outer epidermis and the underlying dermis. The epidermis acts as a tough barrier, with keratin and immune cells helping to block pathogens. The dermis houses sweat glands, oil glands, hair follicles, and a rich network of blood vessels; sweat helps cool the body, while blood flow and sweat production manage temperature and moisture levels. The combination of a protective barrier and temperature/moisture regulation is unique to the skin, making it the system described. The nervous, urinary, and musculoskeletal systems perform other essential roles but do not comprise the epidermis and dermis.
