The immune system works mainly through the joint collaboration between the immune organs, immune cells and immune molecules, so as to destroy the invading bacteria or viruses and expel them from the body.
Normally, when a germ or virus enters the body, macrophages in the immune system will attack, encapsulate it and break it down into microbial fragments by enzymes to form antigens.
The T-cells in the immune system then respond immediately by producing a lymphokine substance to activate the T-cells. The activated immune system produces a type of T-lymphocyte that is highly lethal and through which it produces specialized B-lymphocytes and antibodies.
The killing T-lymphocytes are able to find the already infected human cells and destroy the infected cells, preventing further reproduction of the disease-causing microorganisms.
Secondly, while destroying the infected cells, the immune cells also produce antibodies that bind to the disease-causing microorganisms inside the cells, rendering them useless in causing disease.
After the first infection is suppressed, the immune system will record all the processes of the invasion of the disease-causing microorganisms in the form of antibodies, so that if the body is invaded by the same disease-causing microorganisms again, the immune system will be able to react easily, accurately and quickly to destroy the invading disease-causing microorganisms.
If there is any abnormality in the functioning of the immune system, it is recommended to consult a doctor and follow the doctor’s instructions.
