One of the skin’s six functions that aids its ability to stretch and return is

• A. Heat regulation
• B. Absorption
• C. Secretion
• D. Excretion

Answer: (B)

Stretchability and return rely on the skin’s ability to stay hydrated and pliable. Absorption is the function that directly ties to this because it covers the skin’s capacity to take in moisture and topical ingredients. When the outer layer and underlying tissues hold more water, the skin becomes softer and more flexible, allowing it to stretch with ease and rebound more readily after deformation. The other functions—regulating temperature through sweating, producing oils, and removing waste—don’t directly enhance the skin’s mechanical pliability, so absorption best explains why the skin can stretch and spring back.
