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
