During the break Jeremy pulls out his snack that he had grabbed from his locker, he has packed two delicious fudge covered brownies. Naturally while ingesting such a delightful dessert the fudge on the brownies spread across Jeremy’s face and hands, after finishing his snack he licks his fingers clean. Unfortunately the bacteria contracted from the doorknob which transferred onto his hand has made its way inside of Jeremy's mouth, the mucus within Jeremy’s throat is unable to prevent this bacteria from entering his system. Jeremy has now been infected by the influenza virus!
Once the virus has entered Jeremy’s body it begins to take up necessary resources in order to duplicate and overtake cells, the natural killer cells patrol the blood identifying defective cells and killing them by attaching to the cell and entering enzymes, these enzymes will cause the cell to destruct. Macrophages also known as guard cells also ingest the virus through phagocytosis however this influenza virus has duplicated at a faster rate than what the natural killer cells and Macrophages can handle so they need to call for backup
Ready to take over my friends
Dude he's about to eat us run!
Jeremy's second defense line was unable to destroy the foreign antigen so therefore the helper B cell must come to the rescue. A helper T cell is also activated, the helper t cell cell determines which antibody is necessary to attach to the virus in order to destroy it. Once the T cell has identified what antibody is needed the B cell will produce it.

Okay well I don't know whats keeping you from telling me, I can't make it without your expertise
