The skin is a first-line defense against infection.

B. Increasing dehydration through water loss:
Incorrect. The skin prevents excess water loss; it is a barrier, not a source of dehydration.

C. Decreasing the wastes excreted:
Incorrect. Skin helps excrete wastes (e.g., urea, salts), not reduce excretion.

Skin sweats and vasodilates/vasoconstricts to maintain thermal balance.

E. Support of wound healing:
Skin contains cells involved in tissue regeneration and repair.
