Basophils
Circulate blood
Two pro-inflammatory chemical-secreting cells
Basophils
Mast cells
Bacteria
Single called
1-2 micrometers
Inflammation
Release of chemicals
Vasodilation
Recruitment of immune cells
Delivery of plasma proteins
Vaccines produce
Artificially acquired active immunity
Antibody titer
Antibody concentration in the blood
Cytotoxic T cell
Destroys infected cells with apoptosis
Plasma cell
Produce antibodies
5 day lifespan
Spent in lymph nodes
Helper T cell
Releases interleukins and cytokines to stimulate other cells
Humoral immunity
Antibody-mediated immunity
Phagocytes
Macrophages
Neutrophils
Active immunity
Development of memory cells
Direct contact with antigen
Immune surveillance
Natural killer cells are able to detect unhealthy cells
Opsonization
Marking a target for phagocytosis
Facilitated by interaction of Fc region of antibody with a phagocyte
Antigenic determinant
Binding site
Part of immune system recognizes and binds to foreign molecule
Aka epitope
Prions
Small fragments of infectious proteins that cause disease in nervous tissue
Immunocompetent
Lymphocytes able to bind and respond to an antigen
Eosinophils
Most effective to attack multicellular parasites such as tapeworms
