The Roles Of The Immune, And The Innate Immune System

On a whole the immune system is a protective mechanism designed to perpetuate the survival of the organism. This is achieved by preventing the ever eminent, microbial invasion. These microbes present themselves in the form of bacteria, virus, fungi or parasites. The immune system can been subdivided into two parts. The innate immune and the acquired immune system, both function to protect against invading organisms, and while they differ in numerous ways their main point of differentiation is how they respond to the situation. That however is for a \later discussion. To protect the organism against these microbes, the immune system must be able to discriminate between what is self –apart of the organism- and what is not.

It is composed of protein molecules, specialized white blood cells and tissues. The min players of the innate immune system are the specialized cells and the protein molecules. These specialized cells are called Dendritic and mast cells, neutrophils, Natural killer cells and the macrophages. The majority of these cells are phagocytes, which means that they ingest the pathogens. “The process of a cell ingesting a microorganism, another cell, or cell fragments is called phagocytosis, and cells that ingest are called phagocytes” (Delves 2013. In the event of an immune response' the first line of defense, the skin or subsequent mucosal membrane has been breached. The second line of defense is our innate immune system. The components thereof are: Dendritic, mast cells and macrophages, all found in the basement membrane of the mucosal membrane and the skin. Once they receive signals of penetration of the barrier, they become phagocytic cells and also antigens presenting cells. With the consumption of its target the macrophage releases the remnants of the pathogen as well as protein molecules in the surrounding interstitial
