Innate Immunity or non Specific Immunity
Immunity is the ability of the body to resist almost all types of organisms or toxins that tend to damage tissues and organs of the human body.
Innate Immunity or non Specific Immunity is a type of immunity that results from gereral processes rather than from processes direct at specific diseases.
Below are examples of innate immunities
1. Phagocytosis of bacteria and other invaders by white blood cells and cells of the the tissue macrophage system.
2. Destruction of swallowed foreign organisms by the acid secretion of the stomach and digestive enzymes.
3. Resistance of the skin by organisms.
4. Presence in the blood of certain chemical compounds that attach and destroy foreign organisms or toxins. some of these compounds are lysozyme - a polysaccharides which react with and destroy gram positive bacteria.
5. Natural Killer lymphocytes that can recognize and destroy foreign cells, tumor cells and even some infected cells.
Innate or Not Specific Immunity
According to National Institutes of Health, innate, or nonspecific, immunity is a defense system that you are born with. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response. Examples of anatomical innate immunity include:
- Cough reflex
- Enzymes in tears and skin oils
- Mucus, which traps bacteria and small particles
- Skin
- Stomach acid
Innate immunity also comes in a protein chemical form, called innate humoral immunity. Examples include: the body's complement system and substances called interferon and interleukin-1
If an antigen gets past these barriers, it is attacked and destroyed by other parts of the immune system.
