 | Term | Definition |
| |
Antimicrobials |
Group of proteins that inhibit bacterial/viral growth |
| |
Interferon |
A protein produced by a cell thats infected with a virus; diffused into other cells to prevent replication/spread of viruses |
| |
Complement |
Group of inactive proteins that are found in plasma and activated by bacterial invasion; enhances body's immune responses |
| |
Transferrin |
Inhibits bacterial growth by reducing available iron |
| |
Fever |
Excessively high body temperature; inhibits bacterial growth; speeds up metabolism, which hastens repair actions |
| |
Inflammation |
When cells or tissues are damages by chemicals, heat, or pathogens; redness, heat, swelling, pain |
| |
Vasodilation |
Increases blood flow; increases blood vessel permeability |
| |
Increases vasodilation |
Histamine, kinins (polypeptides, prostaglandins (lipids), leukotrienes, complements |
| |
Phagocyte migration |
Relies on chemotaxis and diapedesis; blood accumulates and neutrophils and monocytes squeeze out of the blood vessel walls |
| |
Tissue repair |
Phagocytes eventually die after their task complete (formation of pus); continues until pus is reabsorbed or leaks into a cavity |
| |
Abcesses |
When pus cannot drain out of an area |
| |
Ulcer |
When the layer of tissue over the pus becomes an open sore |
| |
Priming |
Where the immune system recieves an intial exposure to a pathogen before it can defend itself from it at a later time |
| |
Lymphocytes |
Developed from lymphoid cells in red bone marrow; carry out special immune responses |
| |
B cells |
Lymphocytes that mature in red bone marrow |
| |
T cells |
Lymphocytes that mature in the thymus |
| |
Antigen receptors |
Surface proteins that B and T cells acquire through maturation that recognizes specific antigens |
