A) causes a decrease in the production of macrophages and lymphocytes, thus increasing the risk of infection. B) commonly destroys the stratum corneum, the deep dermal layer of the skin, and causes nerve damage.

D) triggers mast cells to degranulate and synthesize special chemical mediators, which causes the injured area to become warm and red.
