Chapter 14 Flashcards
What are lysozymes?
Enzyme that attacks peptidoglycan bonds that is found in tears an saliva
Define GALT
Gut associated lymphoid tissue (peyer’s patches and the appendix)
Funcitons of GALT
Provides immune function from intestial (GUT) pathogens, and GALT provides antibodies
List the GRANULAR leukocytes
Neutrophils, eosinophils, and basophils
List the AGRANULAR luekocytes
Lymphocyes and Monocytes
Describe neutrophils
Lavender colored, weird lobes, and are the most common luekocytes (55%-90%)
Function of neutrophils?
Phagocytosis
Compare Basophils and Eosinophils
Basophils- bilobed, dark blue, and very rare. Similar to mast cells
Eosinophils- bilobed, orange/red, and contain many chemicals (peroxidase, lysozyme, digestive enzymes, and inflammatory chemicals)
What do Eosinophils mostly function in?
Allergic reactions and fighting against parasites
What do lymphocytes differintiate into?
B-cells and T-cells
Products of B-cells
plasma cells that make antibodies
anti-body mediated immunity
B-cells
cell-mediated immunity
T-cells
Desribe monocytes
largest, kidney shape, no granuals, and become macrophages
What are platelets?
formed elements that are fragments of cells.
Function of platelets
plugging broken blood vessles (hemostasis) and immflamation
What are toll-like receptors?
things that detect pathogen-associated molecular patterns (PAMPS) and “flag” a cell
Macrophages on skin?
Langorhans
Define compliment
A system that creates a cascade effect that adheres to a cell to fix it
What does IL-6 do?
Inhibit viral replication and cell division
Function of spleen
FILTERING BLOOD
