Your immune system are the things that are found inside you that attack foreign invaders and prevent disease from setting in. Dr. David Juan asked me this:
Do you suffer from chronic allergies, yeast infections, colds or respiratory infections? I said, yes, the former and the latter. I mean I have allergy and often have colds and cough. If that is the case, said Dr. Juan, you may have a depressed or weak immune system. In addition, infectious disease experts expect that, during the usual flu season in late fall and winter, chances are various flu outbreaks such as swine or avian can occur. Therefore, he said, it is very important that you fully understand not only your immune system, but also what might weaken or boost it.
In Latin, the meaning of the word "immune" is "protection.” Certainly, your body's immune system is a knotty built-in system as if a network of specialized cells, chemicals, organs and tissues that shields you from attacks by any foreign substance, such as bacteria or viruses.
Your immune system has the capability to tell whether or not a particular substance belongs to your own body or is foreign. Furthermore, it can get rid of any foreign substance quite efficiently by launching a resistant force, which involves the production of antibodies. Now, what are antibodies? They come from specialized white blood cells called the "B lymphocytes." The body will do away of these foreign antigens or pathogens by having the antibodies bolt onto them.
Dr. Juan continued to orient me about antibodies and that they are divided into five different classes, with each class designated by a letter attached to the short form for the word "immunoglobulin" (Ig): IgG; IgM; IgA; IgD; and IgE.
The most common antibody is IgG. It is found mostly in the blood and tissue fluids, while IgA is found primarily in the mucous membranes of the gastrointestinal tracts or the respiratory system.
The topic discussion was becoming interesting when he said there are two types of immune response. At this moment too, I now understand that the immune system is truly very complicated. I learn from him that the "innate" immune system is inborn. I mean it’s already there at birth, and consists of skin, stomach acidity, and the secretions from various mucous membranes coating the respiratory and gastrointestinal tracts. The second immune system is known as "adaptive" which is acquired later in life, such as through vaccinations or exposure to foreign antigen or pathogen. Broadly speaking, the defense mechanisms resulting from these two immune systems can be classified into three groups: 1) physical barriers (skin, mucosa, mucus secretions); 2) immune cells; and 3) antibodies.
These two immune response or better call it the resistant force because they are some kind of home defense team have a few distinctions. This is how my mentor described the two immune systems: The innate system is present in all living beings, while only vertebrates with jaws develop the acquired system. The innate system issues a nonspecific immune response. The acquired system issues a specific response based on what threat has came up. The other is very technical in what sort of chemicals and cellular substances it uses to fight the threat. Innate's best-known ones are natural killer cells, while acquired includes B and T lymphocytes.
