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

There are three stages which occur in inflammatory response. 

The first is vasodilation and increased blood vessel permeability. This stage allows more blood to travel through the site of injury or trauma through the dilation of arterioles and blood vessels. Increased blood permeability allows for defensive antibodies and clotting factors to enter the blood, traveling to the site of injury.

The second stage is the emigration of phagocytes. In this stage, invading microbes are destroyed by neutrophils through phagocytosis. Leukocytosis also occurs as white blood cells in the blood steam increases. Monocytes also work in the inflammatory response as they transform into macrophages which engulf damaged tissue, invading microbes, and worn-out neutrophils.

The last stage is tissue repair where the damaged tissues in the site of injury or trauma are restored. 

 

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

Humoral immunity is an antibody-mediated response wherein antibodies bind to antigens in blood and lymph. B cell lymphocytes leads this mechanism as this immune cell produces antibodies once certain antigens enters the body.
