Multiple Choice
Which of the following is NOT a primary function of the integumentary system?
A
Production of red blood cells
B
Sensation of touch
C
Regulation of body temperature
D
Protection against pathogens
Verified step by step guidance1
Step 1: Begin by reviewing the primary functions of the integumentary system. The integumentary system includes the skin, hair, nails, and associated glands. Its main roles are protection, sensation, thermoregulation, 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 'Sensation of touch.' The integumentary system contains sensory receptors that detect stimuli such as pressure, temperature, and pain, making this a primary function.
Step 4: Evaluate 'Regulation of body temperature.' The integumentary system helps regulate body temperature through mechanisms like sweating and vasodilation or vasoconstriction of blood vessels in the skin.
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.
