Answer the following questions:

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

Inflammation is the body's non-specific defense reaction to tissue damage, and its four defining symptoms are redness, pain, heat, and swelling. There are generally three parts to this process. Specifically, phagocyte migration into the interstitial fluid, vasodilation and enhanced blood vessel permeability, and tissue regeneration.

Vasodilation and Increased Blood Vessel Permeability constitute the initial step. Arterioles are dilated and capillaries become more permeable at this stage, allowing for higher blood flow and the free passage of other chemicals. This main response is also influenced by histamine, complements, kinins, prostaglandins, leukotrienes, and others. These procedures work to assist get rid of dead cells and microbial poisons.

Within an hour, phagocytes like neutrophils arrive to phagocytize invaders. After a fight, neutrophils swiftly disappear and are supported by roving macrophages from monocytes that phagocytize intruders as well as consume worn-out neutrophils and injured tissue. Macrophages that eventually decompose turn into pus together with fluid and tissue cells that have been injured.

 

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

Innate immunity, also known as nonspecific immunity, is the defense mechanism you were born with. You are shielded from all antigens by it. Barriers that prevent hazardous substances from entering your body are a part of innate immunity. 

These barriers serve as the immune system's first line of defense. Cough reflex, enzymes in tears and skin oils, mucus, which traps bacteria and minute particles, skin, and mucus are examples of innate immunity. Innate humoral immunity refers to innate immunity that is protein-based. Examples include the body's complement system, interferon, and interleukin-1 compounds (which causes fever).

If an antigen manages to get past these barriers, additional immune system components will attack and eliminate it.
