Verified step by step guidance
1
Step 1: Begin by understanding the integumentary system. The integumentary system includes structures that protect the body, regulate temperature, and provide sensory information. It primarily consists of the skin and its appendages.
Step 2: Identify the structures listed in the question: lymph nodes, hair, nails, and sweat glands. Determine which of these are part of the integumentary system.
Step 3: Recall that hair, nails, and sweat glands are appendages of the skin and are directly associated with the integumentary system. Hair provides protection and sensory input, nails protect the tips of fingers and toes, and sweat glands help regulate body temperature.
Step 4: Understand the role of lymph nodes. Lymph nodes are part of the lymphatic system, which is responsible for immune responses and filtering lymph fluid. They are not associated with the integumentary system.
Step 5: Conclude that the structure not considered part of the integumentary system is lymph nodes, as they belong to the lymphatic system rather than the integumentary system.
