Self Quiz for "Bacterial Pathogenesis: Factors that Damage the Host"
1. The Ability of PAMPs to Trigger the Production of Inflammatory Cytokines that Result in an Excessive Inflammatory Response
a. Overall MechanismStudy the material in this section and then write out the answers to these questions.
Do not just click on the answers and write them out. This will not test your understanding of this tutorial.
1. Matching:
_____ Intercellular regulatory proteins produced by one cell that subsequently bind to other cells in the area and influence their activity in some manner. Regulate body defense mechanisms. (ans)
_____ Defense regulatory chemicals that promote an inflammatory response by enabling white blood cells to leave the blood vessels and enter the surrounding tissue, by chemotactically attracting these white blood cells to the infection site, and by triggering neutrophils to release killing agents for extracellular killing. (ans)
_____ A condition where bacteria enter the bloodstream causing harm. (ans)
_____ A decreased volume of circulating blood. (ans)
_____ Reduced delivery of nutrients and oxygen via the blood. This can lead to ischemia, a restriction in blood supply that results in damage or dysfunction of tissue. (ans)
_____ Respiratory failure from acute inflammation in the lungs, injury to capillaries in the alveoli of the lungs, and pulmonary edema. (ans)
_____ The formation of clots within the blood vessels throughout the body. (ans)
A. inflammation
B. septicemia

G. septic shock
H. hypovolemia
I. hypotension
J. hypoperfusion
2. Define hypotension and describe the biological mechanism behind 3 factors that contribute to hypotension. (ans)
3. Define hypovolemia and describe the biological mechanism behind 3 factors that contribute to hypovolemia. (ans)
4. Define hypoperfusion and describe the biological mechanism behind 3 factors that contribute to hypoperfusion. (ans)
5. Describe the biological mechanism behind ARDS and how ARDS contributes to hypoperfusion. (ans)
6. Define pyroptosis and state its role in inducing inflammation. (ans)
