Which organ system protects the body and is composed of skin, hair, and nails?

Explanation:
Protection through a barrier is what the integumentary system does. It is composed of skin, hair, and nails, forming the outer shield that guards against pathogens and minimizes water loss. The skin also houses sensory receptors and helps regulate body temperature, while hair and nails provide additional protection. Other listed systems have different roles—hormonal signaling for the endocrine system, immune response and fluid balance for the lymphatic system, and nutrient processing for the digestive system. So, the organ system made up of skin, hair, and nails that protects the body is the integumentary system.
