1. Briefly describe the process of inflammation in an area that has been traumatized.

In an area that has been traumatized, during inflammation, the blood vessels increase in diameter along with the permeability of capillaries, then emigration occurs wherein phagocytes from the blood arrive at the site of infection where they fight off pathogens, then finally, when infection subsides, the tissue repairs. Signs and symptoms of an inflammation are pain, redness, immobility, swelling, and heat.

2. Choose one type of Immunity (Innate and Humoral) and explain how its mechanism protects our body.

One type of immunity is the innate immunity which is a nonspecific immunity that has a rapid response. The body's first line of defense are the skin and mucous membranes as they are surface barriers preventing entry of pathogens in the body. When pathogens enter the body, there would be the phagocytes neutrophils and macrophages which ingest pathogens by phagocytosis, natural killer cells that kill by apoptosis, and inflammation which isolates an area to prevent spread of damage and calls on cells and molecules to kill pathogens present at the site of damage.
