Your First Patient of the Day Is Complaining of Pain

Your first patient of the day is complaining of pain in the area of his new tattoo. When you examine the tattoo, you note that the area around it is firm, red, and swollen. There is no evidence of pus, and your patient has a normal pulse, and no fever. You tell your patient that you have seen this type of response to a tattoo before, and that it is called a granulomatous reaction. You give him more information on the condition
-Your patient doesn't understand all of the cell names that you have used. You educate him on the role of each cell type. One cell type that plays a role in adaptive immunity rather than innate immunity. Which cell is this?

A) Neutrophils-type of phagocytic cell in the blood that quickly move to infected tissues, where they engulf and destroy invading microbes.
B) Macrophages-type of phagocytic cell that resides in tissues, engulfing invaders and debris, and producing pro-inflammatory cytokines.
C) Dendritic cells-antigen-presenting cells that "show" antigens to T cells, playing an essential role in their activation.
D) Eosinophils-primary role is to rid the body of parasitic worms; also involved in allergy.
E) Mast cells-tissue cells that are important in the inflammatory response and immediate allergic reactions.
