____________ refers to the defenses that target a specific pathogen
adaptive / specific immunity
T / F - innate immunity is often slower to reaction but can maintain immunological memory

where are innate immunity parts found throughout the body?
near entry points
what types of cells are included in innate immunity?
dendritic cells
macrophages
monocytes
phagocytes
neutrophils
what types of cells are included in adaptive immunity?
B cell
T cells
________ cells secrete antibodies that bind to antigens and destroy the invader
B cells
______________ cells recognize antigens displayed on cells and can directly attack infected cells
T cells
____________ produces all the leukocytes that participate in the immune system
bone marrow
____________ is a location of blood storage and B cell activation
spleen
B cells are activated and turned into ___________ to produce antibodies
plasma cells
because plasma cell antibodies dissolve and act in the blood (rather than within cells) this division of adaptive immunity is called _____________
humoral immunity
where do T cells mature?
thymus
T cells are the agents of _____________ immunity because they coordinate the immune system and directly kill virally infected cells
cell mediated immunity
