Briefly describe the process of inflammation in an area that has been traumatized.
Inflammation is a defense mechanism of the body and it is mainly done in three basic stages. First is vasodilation and increased blood vessel permeability. This stage increases the blood flow in the traumatized area, delivering defensive antibodies and clotting factors, as well as removing toxins. The second stage is emigration of phagocytes which then leads to the creation of pus. Lastly, tissue repair happens.

Choose one type of Immunity (Innate and Humoral) and explain how its mechanism protects our body.
Innate immunity is a type of non-specific immunity wherein the response to a certain pathogen is almost immediate without the need for prior exposure. Innate immunity protects the body through two lines of defense. In the first line of defense: the skin and the mucus, the body tries to eliminate and avoid pathogens from entering the body and causing diseases. If the first line of defense fails, the pathogen is met with the second line of defense which consists of antimicrobial substances, natural killer cells and phagocytes, process of inflammation, and the process of fever. The second line of defense protects the body by eliminating or neutralizing the pathogens that have penetrated the first line.
