Tumors in the mouth (oral cancer) and throat (oropharyngeal cancer) include both benign (not cancer) and malignant types. Benign tumors, although they may grow and penetrate below the surface layer of tissue, do not spread by metastasis to other parts of the body.
Innate Immunity. The innate immune system is also known as the nonspecific immune system, which provides the first line of immunological defense against infection. The molecules and the receptors of the immune system provide a broad range of protection, so that it is also referred to as ânatural immunityâ.daptive Immunity. The adaptive or specific immune system mainly attacks the specific invaders. It consists of highly specialized cells called thymus-derived T lymphocyte cells and bone marrow-derived B lymphocyte cells.
It is non-specific and is a barrier to the outside world. Your body has various non-specific defenses to path â¦ ogens such as bacteria and viruses. But overall the non-specific defense system is made up of skin, epithelial tissue, and mucous membranes which are always on and preventing pathogenic attacks so to speak.And then you have preventative measures in your blood and in your body.he main non-specific defenses consist of: Lysozymes-such as teardrops which attack bacterial cell walls causing the cell to burst or lyse. Ciliated Epithelia-which are hairlike fibers that can catch pathogens and dispose of them.
