IntroductionWound healing is the final process of inflammation in which tissue architecture and function have been repaired after injury.[1] Basically, before the wound heals, inflammation occurs which helps to eliminate the harmful agents and if elimination is not possible, the inflammation helps to limit the effects caused by the harmful agents. Finally, it prepares the injury site for the healing process. agents that cause the injury.[1] Without inflammation, the wound would never heal because infections persisted at the injury site.[1] There are two types of inflammation: acute inflammation and chronic inflammation. Acute Inflammation Acute inflammation can be triggered by stimuli such as immune reactions, tissue necrosis, trauma, and infections.[1] It is a rapid response to injury or foreign substances that transport leukocytes and plasma proteins to the site of injury.[1] Vascular changes and cellular events are two major components of acute inflammation.[1]• Vascular changes: Acute inflammation can cause vasodilation of blood vessels. Vasodilation of blood vessels results in increased blood flow to the site of injury, thereby causing erythema (redness) and warm features.[1] Vasodilation and increased blood flow then lead to an increase in intravascular hydrostatic pressure, allowing fluid (transudate) to flow from the capillaries into the tissues.[1] The fluid then accumulates in the extravascular spaces, causing a condition called edema.[1]• Cellular events:...... middle of paper ......ng is a chronic disease such as diabetes. The diabetic patient's wound is very difficult to heal because it involves several mechanisms. Thus, it is very important for diabetic patients to take good care of themselves in the event of an injury, as the healing process can be difficult. Works cited1. Vinay Kumar, Ramzi S.
