◉ these 2 hormones dilate the vessels. Answer: histamine and
bradykinin
◉ these travel to the injury. Answer: fluid, WBCs, and platelets
◉ WBCs do this. Answer: phagocytize foreign matter and debris
◉ type I. Answer: immediate hypersensitivity
◉ immediate hypersensitivity. Answer: allergy or atopic disorder,
antigen is seen by b cells and it makes an antibody
◉ symptoms. Answer: hives, nasal discharge, bronchial asthma,
allergic gastroenteritis, anaphylaxis
◉ an oversupply of histamine after inflam causes. Answer:
contraction of smooth muscle, over dilation of capillary beds which
causes capillary leak
, ◉ every exposure causes. Answer: more histamine and antibodies to
be made- worse reaction over time
◉ type II. Answer: cytotoxic hypersensitivity
◉ cytotoxic hypersensitivity. Answer: Antibodies attack antigens on
cell surface, antibody mediated cell lysis
◉ cytotoxic hypersensitivity example. Answer: blood transfusion of
wrong type
◉ Type III. Answer: immune complex hypersensitivity
◉ immune complex hypersensitivity. Answer: antigen combines
with antibody and deposits in tissue, tissue damage results, may be
systemic (Lupus) or localized (RA)
◉ type IV. Answer: delayed hypersensitivity
◉ delayed hypersensitivity. Answer: recognizes antigen, doesn't do
anything, then overreaction. T cell mediated, T cell attack does not
occur until days after initial exposure
