- Briefly describe the process of inflammation in an area that has been traumatized.
- The process of inflammation in an area that has been traumatized starts with an increase in the diameter of the arterioles (vasodilation) as well as an increase in the permeability of the capillaries. Second stage would be the emigration of phagocytes from the blood into the interstitial fluid where phagocytes will ingest and destroy microbes and cellular debris. Lastly, tissue repair or regeneration will occur as the final stage of the inflammatory response.
2. Choose one type of Immunity (Innate and Humoral) and explain how its mechanism protects our body.
- Innate immunity is the first immunological mechanism for fighting against an intruding pathogen and its aim of causing disease. It involves barriers such as (1) the first line of defense (external physical and chemical barriers provided by the skin and mucous membrane) and (2) the second line of defense (internal defenses such as antimicrobial substances, natural killer cells, phagocytes, inflammation, and fever). The first line of defense is the first barrier for foreign substances trying to penetrate the body. Meanwhile, when pathogens penetrate the first line of defense, they then encounter the second line of defense, which is a nonspecific resistance that destroys pathogens in our body.
