4) The lymphatic system…
a) Is a series of blood vessels that carry white blood cells to the lymph nodes.
b) Is a very important aspect of our 2nd line of defense.
c) Maintain our blood volume by collecting excess fluid that will leak out of capillaries when they
are dilated and leaky because of histamines.
d) Consists only of lymph nodes that hold our B and T cells.

b) B cell- it will work through direct cell to cell contact
c) T cell- it will work indirectly through antibodies
d) B cell- it will work indirectly through antibodies
7) What does it mean for an antibody to “neutralize” a virus?
