The Immune System And Skin

There are many ways that skin relates to the immune system. The skin is our body's first line of defense. In order for pathogens to get into our body, they have to get through the skin. The skin also helps the immune system by keeping your body at the right temperature. Without skin, you would get too hot or cold, and therefore be more likely to get diseases.
Without the skin, The immune system would quickly be over ridden by the millions of pathogens that would try to infect your body. In order for pathogens to get past your skin, they must hang on while multiple layers of skin are shed. They then must find a cut or or other way to get past the skin. Once inside the skin, then the body is breached, and then your body is at risk, and therefore the immune system must react and protect the body.

Without the immune system, there are tons of diseases that would harm the skin. one of them is ringworm, a layman's term for fungi on the skin. If not for the immune system fighting off the fungi, we would all have ringworm and/or other infections. The immune system works to stop this by having certain immune cells detect if any of the skin cells have been infected, then send a chemical message to other immune cells, setting off the immune response.
