Verified step by step guidance

Step 1: Begin by identifying the primary functions of the integumentary system. The integumentary system includes the skin, hair, nails, and associated glands. Its main roles are protection, temperature regulation, sensation, excretion, and synthesis of vitamin D.
Step 2: Analyze each option provided in the question. For example, 'Protection against pathogens' is a primary function of the integumentary system because the skin acts as a physical barrier to prevent the entry of harmful microorganisms.
Step 3: Consider 'Regulation of body temperature.' This is also a primary function of the integumentary system, as sweat glands and blood vessels in the skin help maintain homeostasis by cooling or warming the body.
Step 4: Evaluate 'Synthesis of vitamin D.' The skin plays a crucial role in producing vitamin D when exposed to sunlight, making this another primary function of the integumentary system.
Step 5: Examine 'Production of red blood cells.' This is NOT a function of the integumentary system. Red blood cells are produced in the bone marrow, which is part of the skeletal system, not the integumentary system.
