In natural biology, immunity is a natural equilibrium state of multicellular organisms with adequate biological shields to resist infection, or other undesired biological invasion, while at the same time having sufficient tolerance for healthy allergic reactions, and free radical damage. There are basically two types of immunity in humans; one is adaptive immunity that helps in defending against pathogens and their effects; the other is parasitic immunity that is designed to protect hosts from parasites. When it comes to immunity, both adaptive and parasitic immunity can be considered to be part of the normal adaptive immune response.
Adaptive immunity refers to immunity that occurs because of exposure to pathogens or toxins, such as toxins from drug interactions or chemical agents. Adaptive immunity generally involves both innate and adaptive mechanisms and involves specific responses to environmental hazards. Adaptive immunity is usually stimulated by a change in the environment. A number of studies have shown that individuals who are exposed to pathogens may have higher than normal levels of adaptive immunity, in comparison to those who are not exposed to these dangers.
Parasites are known to affect the functioning of the immune system. Parasites have been known to inhibit the natural protective response of the immune system, resulting in an immune system malfunction or over-stimulation, which may then result in opportunistic infections, allergies and diseases. The exact mechanism for this type of parasitism is unknown, but the most common cause is believed to be the direct introduction of bacteria or viruses into an organism. Parasites may also over-feed, resulting in the consumption of a high percentage of an organism’s cellular material in a short period of time, leading to the organism being overtaxed and incapable of producing the necessary antibodies.
Antibodies are one way that the immune response functions. Antibodies are produced by the body to respond to foreign objects or substances that the body has encountered during normal life. The antibodies attack and eliminate the foreign object by identifying and destroying its protein molecules and destroying it by interfering with its ability to perform its functions. Although the immune response is essential for the normal functioning of a healthy body, the immune response is also under the control of many factors, including age, gender, lifestyle, immune system type, genetic make-up, hormones, diet, and certain environmental factors. It is often said that we are genetically programmed to be “immune” to what we come across.
Natural immunity is actually an evolutionary reaction that the body has developed to defend itself from infectious and parasitic agents. While there is some evidence of natural immunity in modern society, it is often thought to be underdeveloped, with a lack of protection against disease due to poor nutrition and other factors. Natural immunity is also often referred to as a self-defensive immunity that is often called up to date, as it is more than a defensive measure. Natural immunity is also a kind of defense against disease. Natural immunity can provide a good defense against infection without the use of drugs or medicines.
Parasites are not the only danger to human health, however, with pathogens, allergens and chemicals being the major concerns in modern society. It is important to learn about the various forms of immunity, as they each represent unique challenges and threats, in order to stay healthy and live a healthy life.
