Verified step by step guidance
1
Step 1: Begin by identifying the components mentioned in the problem: hair, skin, nails, and glands. These structures are external or surface-related and play roles in protection, regulation, and sensory functions.
Step 2: Recall the major organ systems of the human body and their functions. For example, the respiratory system is responsible for gas exchange, the endocrine system regulates hormones, and the digestive system processes food. None of these systems primarily involve hair, skin, nails, or glands.
Step 3: Focus on the integumentary system, which is specifically responsible for protecting the body, regulating temperature, and providing sensory information. It includes the skin, hair, nails, and associated glands (e.g., sweat and sebaceous glands).
Step 4: Understand the role of the integumentary system in maintaining homeostasis. For example, sweat glands help regulate body temperature, and the skin acts as a barrier against pathogens.
Step 5: Conclude that the correct answer is the integumentary system, as it encompasses all the structures mentioned in the problem.
