(28 cards)
Pathogen
organism that harms the host
examples of pathogens
Bacteria, Virus, Fungi, Protists (Please Bring Food Rick!)
what is the function of the immune system
protect the body from pathogens
what are the components of the lymphatic system

Spleen
clean blood of dead cells & pathogens
Peyers Pathces

get pathogens out of respiratory tract
glandular secretions
destroys bacteria
gastric secretions

move white bloods cells to stop infection
physical examples of phagocytes working
Redness, Tissue Repair, Fluid Seaping (Ready? Finger Time)
Dendritic Cell
Present antigen to T Cells
Neutrophils
shorts living; respond to invaders
Basophils
Alert the body of invasion
Eosinophils
help with multi ceullular invasions
What are the different types of Macrophages
Dendritic Cell, Neutrophils, Basophils, Eosinophils (Bryan Eventually Nose Dives)
What are the different types of Lymphocytes
Helper T Cells, Killer T Cells, Suppresser T Cells, Memory T Cells (Help Me Kill Somoeone)
Helper T Cells
fight infection by producing antibodies
Killer T Cells
destroy cells infected with virus, tumor, pathogen
suppressor T Cells
tells other T Cells to stop fighting infection
