Question:

Which of the following is a function of the epidermis?

A Protects underlying tissues from abrasions, heat, microbes, and chemicals.
explanation

The epidermis, as the outermost layer of the skin, protects underlying tissues from abrasions, heat, microbes, and chemicals. It functions as a major component of the innate immune system (the “general” immune system that targets anything seen as “foreign”). It is avascular, so it does not contain blood vessels. Lipid-containing cells are found in the subcutaneous layer.
