In addition to fluid, some exudates will include what we have referred to previously as formed elements and can lead to liquifactive necrosis. 1. Inflammation that is characterized by the presence of this type of exudate can be called… 2. What is the most common cause of this type of inflammation? 3. Is this type of inflammation more often acute or strictly chronic?

Various cells act as sentinels that can detect danger and then release chemical mediators of inflammation. Which one of the following cells releases histamine after detecting danger?
Environmental stresses trigger changes in gene expression th…
Environmental stresses trigger changes in gene expression that modulate a cell’s sensitivity to injury. This has been clearly demonstrated by applying low level stress to cells prior to subsequent exposure to a higher level stress. Under these circumstances, cells that receive the pretreatment are better able to moderate the impact of higher level stress than cells that received no pretreatment. Provide at least one example of a mechanism that can explain this phenomenon.

Digestive enzymes can be released from phagocytic cells. Besides the obvious benefit of digesting pathogens, digestive enzymes can also regulate inflammation. How do they do this?
