Verified step by step guidance

Step 1: Begin by understanding the integumentary system. The integumentary system is primarily responsible for protecting the body, regulating temperature, and providing sensory information. It includes structures that are external or closely associated with the skin.
Step 2: Review the structures listed in the options. The first option includes skin, hair, nails, and sweat glands, which are all external structures and directly part of the integumentary system. The other options include internal systems like the cardiovascular system (heart, blood vessels, and blood), skeletal system (bones, cartilage, and ligaments), and respiratory system (lungs, trachea, and bronchi).
Step 3: Match the structures to their respective systems. For example, the cardiovascular system is responsible for transporting blood, the skeletal system provides structural support, and the respiratory system facilitates gas exchange. None of these are part of the integumentary system.
Step 4: Focus on the first option (skin, hair, nails, and sweat glands). These structures are directly involved in the functions of the integumentary system, such as protection, thermoregulation, and sensory reception.
Step 5: Conclude that the correct answer is the first option, as it lists the structures associated with the integumentary system. The other options describe systems unrelated to the integumentary system.
