1. Briefly describe the process of inflammation in an area that has been traumatized.
Inflammation is referred to as a nonspecific defensive response of the body to tissue damage wherein symptoms such as pain, redness, immobility, swelling, and heat can trigger this response. The inflammatory response is described through three (3) stages: 1) Vasodilation and increased permeability of blood vessels, 2) Emigration of phagocytes, and 3) Tissue repair.
The first stage is responsible for the dilation of arterioles and increased permeability of capillaries that remove microbial toxins and dead cells through the flow of blood and defensive proteins to the damaged area.
The second stage is where phagocytosis occurs wherein foreign materials such as microbes in the damaged area are engulfed and killed by phagocytes.
2. Choose one type of Immunity (Innate and Humoral) and explain how its mechanism protects our body.
Innate immunity is a nonspecific defense system present at birth. It refers to the external and chemical barriers that protect the body from pathogens by preventing it's spread and movement. These include the skin and mucous membranes which are the body's first line of defense.
