Ex: skin, mucous membranes, hair: second line. Memory cell from previous experience, creates memory for next time you encounter the pathogen. Phagocytic cells (2nd and 3rd lines of defense: neutrophils. Respiratory bursts: neutrophils spit out antibacterial toxins: eosinophils. Parasites, allergens: production of toxic protein & secrete antihistamines: basophils. Antimicrobial proteins: short term resistance against bacteria and virus.

Cell death: 3 ways that pathogens come into the body. Antigen presenting, (cid:862)announ(cid:272)es it"s a pathogen(cid:863) (anti(cid:271)ody dependent) Ex: a kid in a penn state shirt walking into a temple party on game day. Virus or bacteria tries to blend in with your own cells (antibody-independent) Ex: a penn state student walking into a temple party wearing a temple t-shirt on game day.
