Final answer:
The redness of inflammation is primarily caused by increased blood flow and capillary permeability, as a result of histamines and cytokines released during the inflammatory response.
Step-by-step explanation:
The reversible inflammatory response process of the pancreatic Pacinian corpuscles that leads to the redness of inflammation is primarily due to increased blood flow and capillary permeability. Inflammatory mediators such as histamines and cytokines cause these effects by promoting vasodilation and allowing plasma to leak out and form interstitial fluid, making tissues swell. This is part of a very basic form of immune response, which includes the activation of immune cells and the release of cytokines to fight off pathogens and start the healing process.
