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 pathogen. Hope it helped.

Your gonna need to upload an image with the question : )

From our previous experiment, we examined how many drops a penny can hold - and place drops of salt water on the penny after recording 5 trials each, take the average of each solution.
