Which aging change includes reduced elasticity of skin and blood vessels?

• A. Reduced elasticity of skin & blood vessels
• B. Hormonal changes
• C. Immune changes
• D. Reduced stamina

Answer: (A)

Aging brings structural changes in connective tissue that reduce how tissues stretch. Skin loses elastin and its collagen becomes more cross‑linked, so it becomes thinner and less elastic. Blood vessels also lose elasticity as elastin degrades and collagen accumulates, making them stiffer. This combination—less stretchy skin and stiffer vessels—is a classic aging change. While hormonal changes, immune changes, and reduced stamina occur with aging, they describe other aspects (hormonal shifts, immune system aging, or overall energy/fitness) rather than the specific decrease in elasticity of skin and vessels.
