The concept that I have learned in this week’s discussion if how innate immunity defends our body from penetrating microbes or foreign objects that may damage our immune system and cause havoke inside our body. It is like raising an awareness to protect our body especially the first layer of defense which is the skin. All through out the years, I’ve been protecting my skin for the sake of my physical appearance but learning how important this layer really is, I would be able to protect my skin more and avoid anything that can cut or damage my skin which can allow dirt, dusts, or any bacteria that may penetrate my body.
