Immune System 1st Line of defense 2nd line of defense Cillia
Mucus membranes
Anti microbial proteins
Gastric juices Targets invading antigens Consists of Phagocytes
monocytes) NK cells Compliment
system Interferons Inflamatory
Response Basophils Release
Histamine Vasodialation Phagocytes 3rd line of defense Targets antigens T cells B cells Helper T cell Cytotoxic T cell Create B memory
cells after infection Active immunity create antibody
mediated response APC binds to B cell B cells divide
into plasma cells this releases
antibodies Produce antibodies
that bind to antigens they are 'Y' shaped Helper T cells
Release Interlukins
