The stem cell divides, producing undifferentiated stem cells that are of what
lineage? myeloid or lymphoid
What cells do myeloid precursors turn into? red blood cells, white blood cells, and
platelets
What cells do lymphoid precursors turn into? specialized white blood cells called
lymphocytes
Granulocytes are basophils, eosinophils, neutrophils
Agranuloyctes are T lymphocytes, B lymphocytes, monocytes
What two type of immunity make up the immune system? innate and adaptive
What line of defense is innate immunity? first
What is the role of innate immunity? is to mount a non-specific response to a non-
self entity that does not retain memory of the entity
What types of things does innate immunity respond to? skin, mucous
membranes, normal flora of the skin and gut as barrier or bacterial protection
against foreign substances AND cellular components such as phagocytes, natural
killer cells, granulocytes, and macrophages
If innate immunity proves to be insufficient, what is mobilized? adaptive immunity
Adaptive immunity leads to what? immune system memory related to a
pathogen or foreign substance
What are the three parts of adaptive immunity? humoral immunity, cell
mediated immunity, regulatory t-cells
What is humoral immunity made up of? b lymphocytes, memory b cells, and
plasma to produce immunoglobulins or antibodies
What is cell mediated immunity dependent on? cytotoxic t-cells, helper t-cells
and their cytokines
What are regulatory t-cells also known as? supressor t-cells
What do regulatory t-cells do? regulate the immune response to prevent
autoimmune reactions and limit inflammatory responses
What are cytokines? cytokines are secreted by lymphocytes with the intention
of stimulating macrophages and cytotoxic t lymphocytes to identify and kill
pathogen infected cells or tumor cells
What do proto-oncogenes do? regulate normal cell growth and division.
