Document Summary
Skin: 30-50 layers of simple squamous to keep foreign invaders out. Any place there is a opening of the skin. Any laceration in the skin a foreign invader can get in. Mucous membranes: any place you have epithelial cells lining there is goblet cell. Goblet cell is inside of epithelial cell produces mucous and lines the inside of any system. Foreign invaders can get trapped in the mucous membrane. Once something gets caught in mucous membrane neutrophils and other phagocytes eat whatever is trapped in membrane. These contain a ph that foreign invaders can survive in: phagocytes: Free phagocyte: have ability to roam free from tissue to tissue. Fixed phagocyte: don"t leave space can only eat what comes to their location. Looking for non-self cells via the glycocalyx. Paying attention to your own body cells and looking for changes in your cells that have undergone changes in glycocalex to non-normal (cancer cell) Bodies own defenses against your own cancer cells.
