Fight Infections with a healthy Immune system
Human body is one of the most advanced creations of the Almighty and learning about it is a great fun. Same as a machine exhibits a safety mechanism and is equipped with a defense protocol, the human body too is supplemented with the same attribute. This mechanism helps keep the body protect form all infections and fights any foreign bodies invading the system. As such, one cannot take any risks with this system and make it fall loose. The environment is full of microbes and infectious agents that will affect the body very badly, a strange fact revealed by scientists tell that at any given point of time the body might be fighting a number of infections. The stronger the immune system the body takes lesser time to eliminate the toxins from the body.
Basically, immune system is divided in to two categories:
- Innate immune system.
- Adaptive immune system.
Innate immune system is the default system that stays installed in the human body right from the birth. This system helps protect the body from common infections and has very basic protection ability.
It is characterized by the following properties:
- Response is non-specific.
- Exposure to pathogens leads to immediate maximal immune response.
- No immunological memory exists.
- Present nearly in all forms of life.
As mentioned earlier, this system will fight the basic infections and might lead to maximum exposure. This means that the body will respond very strongly to the pathogen and thus there could be inflammation and other secondary responses.
Adaptive immune system is like new systems getting installed in the body. The body is prepared to fight specific pathogens with specific cells and pathways to carry out effective and complete elimination.
The system has the following characters:
- Responses are specific to a specific pathogen.
- There exists a lag time between the exposure and maximal response.
- Minimal exposure leads to immunological memory.
- Present only in jawed vertebrates.
A striking fact of human immune system is its capability of memorizing the pathogen structure and function. A minimal exposure of a pathogen to the body will generate a memory that can be utilized to fight future occurrences of the same disease or infections. Let me share and example, chicken pox is caused by a bacteria. The pathogen ones in, causes infection and is later eliminated by antibiotics. Next time when the same body is exposed to chicken pox infection, the body will easily eliminate and there will be no symptoms of it. It is a highly specialized capability of human immune system.
Build a Better Immune Defense
There exist a lot of diseases that can occur due to the malfunctioning of ty8e immune system; those are termed as autoimmune diseases. Autoimmune diseases consider the body’s cells as foreign objects and attack them. There are treatments available to handle such conditions.
The immune system is huge and there is no end to its learning. The above text is just a brief idea.
