Corrosive substances can cause irreversible damage to what?

Corrosive substances can cause irreversible damage to what?

• A. Skin
• B. Hair
• C. Human tissues
• D. Nails

Answer: (C)

Corrosive substances cause chemical burns by destroying living cells in tissue. They can produce permanent, irreversible damage to human tissues—such as skin, mucous membranes, and internal organs—because these are living tissues that can be chemically necrotized. Hair and nails are keratinized, nonliving structures, so they aren’t the primary sites of irreversible injury in the same way living tissues are. That’s why “human tissues” is the best answer: it encompasses all the living tissue that corrosives can permanently harm.
