Outer Defenses of the Immune System are just as important as any other part, though they are the least talked about and discussed. And when one looks at the body, it becomes very obvious that the body is designed to keep pathogens out, hence the need for the outer defenses.
Everyone loves talking about the Inner Defense of the Immune System, they being the Antibodies, B Cells and the T Cells, which we will get onto later, though let’s have a quick look at the first layer.
For a pathogen, the bodies outer defenses consist of the equivalent of a wall, a swamp and a moat.
With the Wall being the bodies skin
The swamp being the mucous membranes
The moat being the stomach acid
So a pathogen and a virus has to get through those layers before it’s even attacked by the Antibodies, the B cells and the T cells.

So let’s quickly see how each aspects of the outer defenses form part of the Immune System

As can be seen, the world of the Immune System, and all of it’s information and workings can become complicated very, very quickly and very, very easily, though for a basic understanding we have to keep in mind the gist of what is going on.
For unless one is going to become an Immunologist, one doesn’t need to know all of the details, though an overall understanding will suffice.
The outer defenses of the Immune System, are just as important as the Inner defenses, for it works as a holistic whole
