Briefly describe the process of inflammation in an area that has been traumatized.
- Inflammation is the body's response to tissue damage. It can be characterized as painful, heatness, redness and swelling on the affected part. Inflammation has three basic stages. The first stage is the vasodilation and increased permeability of blood vessels, second is the emigration (movement) of phagocytes from the blood into the interstitial fluid, and, lastly tissue repair. Vasodilation increases the permeability of capillaries and diameter of arterioles which allows more blood to travel immediately to the affected part. Then Emigration happens, Large amount of blood accumulate and neutrophils begin to stick the inner portion of the lining of blood vessels and squeeze through to reach the damaged area. After quite some time, monocytes will then follow neutrophils to the affected area and become wandering macrophages. A collection of dead cells and fluid (pus) will then stay at the affected part and continue to be present until the infection eases.
Choose one type of Immunity (Innate and Humoral) and explain how its mechanism protects our body.
- Innate immunity is a type of an immunity that everyone is born with. Since it is non-specific, it approaches injuries and foreign bodies the same way. It also provides both external and internal defenses for the body such as chemical barriers by the skin and anti-microbial substances.
