How to immune System Work:
Your immune system is an interactive system of organs, white blood cells, and proteins that defends your body against viruses and bacteria, or indeed foreign substances.
Every minute of every hour of every day, we are exposed to dangerous organisms that we inhale or swallow or stick to our skin or irritants. These pathogens will cause disease without our defense mechanisms.
When our system is working, we don't even feel this infection. But if our immune system is compromised, that is, inactive or inactive, we develop infections or other medical conditions.
This is how the immune system works:
Your immune system works to 1 neutralize and destroy pathogens such as bacteria, viruses, parasites, or fungi that enter the body, 2recognize and neutralize harmful substances from the environment, and 3 fight changes in body cells; due to illness.
If our immune system was working to protect us, we would never feel it. But when productivity is impaired, the disease occurs.
To function properly, cells, organisms and substances must be able to distinguish between two types... 'Self' and 'non self'.
'Your' body cells etc. meaning 'non-self', foreign objects, cells, etc. that enter the body. means this is called an antigen.
Your immune system can usually distinguish between its own cells and antigens. For example, the protein on the surface of the cell itself will be different from the protein on antigens such as viruses, bacteria, and fungi. The system can detect these different proteins. Once it finds antigens, it will attack to destroy them.
Your immune system has two parts:
A primary system that functions as a general defense system against pathogens disease-causing organisms and
which remember certain pathogens that are present and will attack them when they appear.
As you can see, the system adapts and learns over time to fight bacterial or viral changes. The two parts of your immune system complement each other in their reactions to the same pathogen.
