Innate Immunity worksheet
(1) From the word bank, assign each term to the immunity heading with which it is associated.
Some terms may fit more than one category and should be placed in all categories that apply.
antibodies in breast milk
lymphocytes
stomach acid, saliva, tears
complement
first line of defense
Passive immunity
generalized response
specific
memory
non-specific
same response every time
cellular response
short-lived antibodies
variable response
barriers
Innate immunity
Adaptive immunity
(2) The two types of phagocytes associated with the innate immune response are
__________________ and ___________________.
List the functions of each:
________________________________ _____________________________________________
(3) Nail biters often have red, warm, and swollen areas around the cuticles. What kind of
response does this condition indicate? ____________________________
Explain specifically why the area is red; why it is warm; and what causes the swelling.

(2) Two types of phagocytes :
macrophages - ingest pathogens and dead cells
neutrophils - release chemicals that kill nearby bacteria (and
themselves)
(3) Nail biters: Inflammatory response
causes:
redness and warmth - increased blood flow to the area, bringing phagocytes
swelling (edema) - fluids leaking from plasma into intercellular spaces, phagocytes engulf
pathogens
