Verified step by step guidance

Step 1: Begin by identifying the primary function of the organ system in question. The problem asks for the system that protects the body and includes skin, hair, and nails.

Step 2: Recall the components of the integumentary system. It consists of the skin, hair, nails, and associated glands, and its primary role is to act as a protective barrier against environmental damage, pathogens, and water loss.

Step 3: Compare the integumentary system to the other options provided: the lymphatic system (involved in immune response and fluid balance), the skeletal system (provides structural support and protection for internal organs), and the muscular system (responsible for movement and posture). None of these systems include skin, hair, and nails as components.

Step 4: Understand why the integumentary system is the correct answer. It is the only system explicitly composed of skin, hair, and nails, and its protective function aligns with the description in the problem.

Step 5: Conclude that the integumentary system is the correct answer based on its components and primary function of protection.
