Q

Hemosiderin

A

is most commonly found in macrophages and is especially abundant in situations following hemorrhage

21
Q

Ankylosing spondylitis

A

Strong genetic inflammation activists with IL1

chronic inflammatory disease of the axial skeleton

involves CD8 T cells, which interact with HLA-B.

usual immunity that results from real-life exposure to a pathogen.

23
Q

Natural, passive immunity

A

fetus gets IgG
passively across the placenta from its mother

the baby gets IgA in mother’s milk if she nurses it

24
Q

Artificial, active immunity

A

: immunity resulting from intentional immunization with vaccines, toxoids, or
other antigenic preparations.
