Anatomical barrier are for example the skin,bony encasements and mucous membranes. 5. Functions of epithelial tissue are secretion, protection, absorption . On the other hand, a similar amount of blood leaking into the abdomen does not destroy tissue because the abdomen has room for expansion. While the relation between blood-brain barrier . Some common forms of psychological barriers are discussed in this study. The root of a term often refers to an organ, tissue, or condition, whereas the prefix or suffix often describes the root. The cell junctions in the blood . The immune system can be divided into two overlapping mechanisms to destroy pathogens: the innate immune response, which is relatively rapid but nonspecific and thus not always effective, and the adaptive immune response, which is slower in its development during an initial infection with a pathogen, but is highly specific and effective at attacking a wide variety of pathogens (Figure 21.2.1).

The simplest way to avoid infection is to prevent the microorganisms from gaining access to the body. Anatomical and physiological barriers together provide this crucial first line of defense against pathogens. The immune system uses white blood cells and antibodies to identify and eliminate organisms that get through the body's natural barriers. The skin is made up of the epidermis and dermis which is dry with a 37 degree Celsius temperature and is also acidic. ; Physiological barriers that contribute to the innate immunity are the body temperature, pH and various soluble secretory products of the mucosa. in response to tissue damage or chromic; for eg. Among the mechanical anatomical barriers are the skin and internal epithelial layers, the movement of the intestines and the oscillation of broncho-pulmonary cilia. Infections that recur in the same ana-tomical site are often due to defective anatomical or physiological barriers and hence should induce a diligent search for such factors. Finally, damaged tissues, for example, damaged cardiac valves, provide a nidus for the establishment of infection. There are many interesting examples of speciation.
