- Musculoskeletal system
- Integumentary system (Correct answer)
- Lymphatic system
- Endocrine system
Correct answer: Integumentary system
The integumentary system (skin, hair, nails) regulates temperature, provides sensory information, and acts as the body's first line of defense against pathogens.
