Response To Injury

There are three main phases to the body’s response to injury. These are inflammation, maturation and the proliferation. The first response is inflammation. This is basically pain and inflammatory of the affected area. This stage can last between 3 and 5 days. The second phase is proliferation. This phase lasts two to five weeks and it is where the body begins to repair the affected area. The final stage is maturation. This stage can last from 3 weeks up to 2 years depending on the severity of the injury. This stage is where the affected area regains some strength so it can be used as it was before the injury.
Inflammation
The inflammatory stage is the first stage in the response of an injury. Inflammation is a response to cell damage within body tissue and is a chain of events that aids in repairing, reforming or even forming new scar tissue. Inflammation occurs when excess pressure, friction, overload, over-stretching or impact trauma is applied to a certain area. There are five main effects of inflammation. The first is swelling. Swelling happens due to the bleeding from torn blood vessels and tissue fluid leaving the cells around the affected area. Swelling also helps to protect the affected are from any more damage. It acts as a cushion around the affected area. The second symptom is pain. The pain comes from the increased pressure to the affected area and damage to the nerve fibres due to the swelling. The third symptom is redness around the affected area. This is due to the vasodilation of the nearby undamaged blood vessels. The fourth symptom is heat. …show more content…
This is the main healing stage of the response. This is where new tissue and a new network of capillaries are formed around the affected area. This allows better circulation and drainage at the affected area. After this fibroblasts begin to be made in the connective tissues and they are responsible for the repair of the affected
