Phagocytes
-cyte
(prefix:Greek) cell
Phago-
(suffix:Greek) eat
helper-T cells
Trigger antibody and cell mediated immune response, initiate production of antibodies and activate T cells
basophils
are capable of ingesting foreign particles and produce heparin and histamine and which induce inflammation, are often associated with asthma and allergies
pathogen
disease-causing agent
Killer-T cells
involved in cell-mediated response; kills cancer cells, virally infected cells, or cells damaged in other ways.
monocytes
made in bone marrow; replenish macrophages and dendritic cells. preform phagocytosis. function in harmony with the T cells to identify and destroy pathogens
t-cells
made in the thymus, play a major role in the immune system
NK cell
play major role in defending against tumours and virally infected agents
Phagocytosis
process in which phagocytes engulf and digest microorganisms and cellular debris
B-Cells
produced in bone marrow; involved in humoral response; makes antibodies against antigens
dendritic cells
provide an enormous surface area for receiving signals from other neurons
surface receptors
recognize pathogens.
mast cells
Cells that produces histamine and other molecules that trigger the inflammatory response; found in connective tissues
Phagocytes
Cells that use phagocytosis to engulf foreign organisms.
neutrophils
Makes up the largest % of white blood cells. A type of WBC phagocyte, which is the most abundant WBC. Its primary purpose is to perform phagocytosis.
macrophages
type of leukocyte that ingests pathogens and then fuses with a lysosome; found in organs
eosinophils
weakly phagocytic of pathogens kill parasitic worms
leukocytes
white blood cells; neutrophils, eosinophils, basophils, monocytes, macrophages, dendritic cells, & lymphocytes
lymphocytes
T-cells, B-cells, & NK cells
