DESCRIPTION: The body's response to injury Inflammation, the most common of all body reactions to injury, is a local reaction of body cells. Injury may be produced by trauma, foreign bodies, chemicals, electricity, heat, cold, pathogenic micro-organisms or pathogens, radiation. In a simple inflammatory process such as a surgical incision, the blood supply to the area is increased. White blood cells and serum leave the bloodstream and surround the injured part.
When no pathogens are present inflammation subsides; the white blood cells devour dead cells (phagocytosis) and return to the bloodstream. Excess fluid is reabsorbed, the wound edges grow together and healing occurs. When inflammation is caused by pathogenic organisms, the same defensive reaction starts. After leaving the bloodstream, the leukocytes (white blood cells) try to kill invading organisms.
Antitoxins and antibodies are two important immune substances that are carried to the area by the blood. If immune sub-stances and...
