Q

DURING THE ACUTE INFLAMMATORY RESPONSE:

  1. TRANSIENT ARTERIOLAR CONSTRICTION IS FOLLOWED BY ARTERIOLAR DILATION, WHICH ALLOWS AN INFLUX OF BLOOD UNDER INCREASED PRESSURE.
  2. CHEMICAL MEDIATORS, WHICH ARE PRIMARILY PRODUCED BY MONOCYTES, CAUSE LOCALIZED CONSTRICTION OF THE VESSELS ADJACENT TO THE AFFECTED SITE.
  3. ACTIVE HYPEREMIA CAUSES THE BLOOD VESSELS TO CONSTRICT, WHICH DIVERTS BLOOD AWAY FROM THE AFFECTED SITE.
  4. INCREASED VESSEL WALL PERMEABILITY FORCES FLUID OUT OF THE INTERSTITIAL SPACES, RESULTING IN CELL SHRINKAGE AND EVENTUAL DEATH.
A
