Innate Immunity Quiz
Question | Answer |
---|---|
First line of defense against infections | Innate Immunity |
Three components of the innate system | Physical barriers, circulating cells, circulating proteins |
What are physical barriers? | Skin and mucus |
Circulating Cells | Neutrophils, macrophage, dendritic cells, natural killer cells, mast cells, eosinophils, basophils |
Circulating Proteins | Lysosyme, complement system |
What is the most important barrier to infection? | Skin |
Other barriers to infection | Respiratory, urinary, GI tract |
What do goblet cells secrete? | Mucin |
What are leukocytes? | White Blood cells |
What cells are non-lymphocytes? | B&T Cells |
Granulocytes | Neutrophils, Basophils, Eosinophils |
Agranulocytes | Monocytes, macrophage, dendritic cells |
Which WBC is the most abundant in mammals? Polymorphonuclear cells, attraction to infection, target extracellular pathogens (bacterial) mechanism of protection- phagocytes, degranulation, NETS | Neutrophils |
Takes up basic dye, releases histime during inflammatory response, helminths, degranulation, binds to IGE antibodies | Basophils |
Orange stain, fights parasites and viral infections, degranulation (modulates)Reactive oxygen- species and paradoxides | Eosinophils |
Differentiate into macrophage or dendritic cells, kidney shaped nucleus, involved in phagocytosis, antigen presentation, and cytokine production | Monocytes |
Found in blood and tissues, phagocytosis of pathogens, cytokine-chemical signals that modulate the immune response | Macrophages |
Dendritic cell |
