1. Briefly describe the process of inflammation in an area that has been traumatized.
Inflammation is the general defense mechanism of the body and it has three basic stages it undergoes upon its response. First off, blood vessels increase in permeability, which is known as vasodilation. In this stage, more blood flows to the injured area as well as antibodies for the initial defense mechanism of the body. Afterwards, emigrations occurs. Phagocytes squeeze through the lining of blood vessels and go to the injured areas. Lastly, to end the inflammation process, the tissue undergoes tissue repair.
2. Choose one type of Immunity (Innate and Humoral) and explain how its mechanism protects our body.
The innate immunity is composed of the first and second line of defense. The first line of defense are the skin and the mucous membrane. The skin acts as a physical barrier against foreign substances while mucous membrane produces viscous mucus that traps or hinders bacteria or microbes from entering the body. On the other hand, the second line of defense is the internal counterpart of the innate immunity. It relies on antimicrobial substances within our bodies, phagocytes, killer cells, and as mentioned earlier, processes such as inflammation to act as an internal defense mechanism when the first line of defense is penetrated.
