What three effects does increased blood flow have on an infection site?

Histamine causes local blood vessels to dilate, increasing blood flow to the area. Increased blood flow brings white blood cells to the infection site, where they can attack pathogens.  The increased blood flow also causes swelling and redness in the infected area.  The whitish liquid, or pus, associated with some infections contains white blood cells, dead cells and dead pathogens
