Define and describe the physical, chemical, and cellular components of the innate immune response. - Physical factors are barriers to entry or processes that remove microbes from the body's surface The epidermis consists of layers of tightly packed epithelial cells that are periodically shed. (makes up dust) That it is dry makes it inhospitable to microbes. Cebum- unsat fatty acids; inhibit growth of persperation Chemical factors are substances made by the body that inhibit microbial gr...
