Order of proportions of WBCs acronym

Neutrophils

Lymphocytes
Macrophages/dendritic cells
Eosinophils
Basophils

granulocyte

3 lymphocyte subdivisions. made in bone marrow, has granules in cytoplasm

lymphocyte

3 types. made in lymphoid tissues. only NK is innate.

chemotaxis

migration of WBC to an area of increased chemical attractants/stimulus

diapedesis

squeezing of WBCs thru BV walls

monocytes

can differentiate into macrophages

acquired immunity

Antigen presenting cells (APCs) capture pathogens and break them down into antigens (AAs).

They display these fragments on their MHC to antigen sensitive cells (T cells),

which allows those T cells to activate and cause an immune response against the pathogen.

APCs

Dendritic Cells - most potent

B cell (lymphocyte)

Macrophages
