PATHOLOGY

Detailed explanation-1: -Inflammation During this phase, white blood cells and some enzymes enter the wound area to stave off infection by clearing bacteria and debris and preparing the wound bed for new tissue growth. Physical characteristics of the phase include inflammation or redness at the wound site, edema, heat, and pain.

Detailed explanation-2: -During the inflammatory phase, damaged cells, pathogens, and bacteria are removed from the wound area. These white blood cells, growth factors, nutrients and enzymes create the swelling, heat, pain and redness commonly seen during this stage of wound healing.

Detailed explanation-3: -These include the hormones bradykinin and histamine. They cause the small blood vessels in the tissue to become wider (dilate), allowing more blood to reach the injured tissue. For this reason, inflamed areas turn red and feel hot.

Detailed explanation-4: -Acute-swelling stage. Sub-acute – regenerative stage. Chronic – scar tissue maturation and remodelling stage.
