Question

Why do you think the inflammatory response involves so many molecules and so many cell types? Why do multiple cells/cell types in the inflammatory process secrete the same molecules?

Answer 1

Inflammatory response involves so many molecules and cell types because they are triggered by so many factors like nonpathogenic factors, pathogenic factors and tissue damage. As there are so many factors we need many molecules and cell types to converge the stimulus to a single response ie inflammatory response.

All types of inflammatory responses have same basic mechanism with same properties like vasodilation, increased BMR, swelling, redness etc and to produce such common responses by damaged tissues, many cell types have to secrete a common set of molecules.
