Innate Immunity

As its name implies, innate immunity is what a person is born with. It is also affected by the vaccinations received as well as the foreign matter and microbes the person is exposed to during their lifetime. Innate immunity functions quickly, effectively and consistently

The innate immune response occurs immediately thanks to phagocytic cells such as monocytes (macrophages and NK cells) and granulocytes (white blood cells). They are able to move through the cell walls of capillaries into the interstitial fluid to kill pathogens. A phagocytic cell identifies the receptor structure on the surface of a microbe and engulfs the microbe in order to recycle it.

Another part of innate immunity is the so-called complement system which consists of proteins in the interstitial fluid that are produced in the liver. They are able to identify and destroy microbes occurring in the interstitial fluid.
