Antibody

Secreted by the plasma cells;Protein that bings to antigen to deactive it

Antigen

Located on cell surface; Surface cell protein used by body for identification

Autoimmune disorder

Disease in which immune system attack and destroys healthy body tissue

Innate immunity

Physical barrier; Non-specific method to fight against infection

adaptive immunity

specific response to pathogen that recognize specific pathogens

Lymph node

Bean shaped lymphatic filter

Leukemia

cancer of white blood cells

Plasma cell

Primary immune response; produces antibodies

Memory B cells

Secondary immune response

Perforin

turn off immune response

natural active immunity

Accidentally exposed to pathogen such as chicken pox

Artificial passive immunity

Being injected with antibodies

Artificial active immunity

vaccination such as the flu shot
