Verified step by step guidance

Step 1: Begin by identifying the integumentary system and its components. The integumentary system primarily includes the skin, hair, nails, sweat glands, and sebaceous glands.

Step 2: Understand the primary functions of the integumentary system. These include protection against environmental hazards, regulation of body temperature, sensory reception, excretion of waste products, and synthesis of vitamin D.

Step 3: Analyze the options provided in the question. Evaluate whether each function aligns with the known roles of the integumentary system. For example, production of red blood cells is a function of the skeletal system (specifically the bone marrow), not the integumentary system.

Step 4: Eliminate options that are unrelated to the integumentary system. Regulation of blood glucose levels is a function of the endocrine system (e.g., insulin production by the pancreas), and synthesis of digestive enzymes is a function of the digestive system.

Step 5: Conclude that the correct answer is 'Protection against environmental hazards,' as this is a primary and well-documented function of the integumentary system, which acts as a physical barrier to protect the body from pathogens, UV radiation, and physical injury.
