Immune system has memory component. How does man make use of it to control disease?
Dear student,
Please find below the solution to the asked query
When the pathogen (microorganism) enters in our body for the first time, our body produces immune response of low intensity called primary response. The primary immune response is carried out with the help of two special types of lymphocytes present in our blood i.e B- lymphocytes and T- lymphocytes. The B- lymphocytes produce the army of proteins called antibodies which kill the pathogen. Some of the B cells called memory B cells and antibodies remain stored as memory in our blood. If the person is attacked by the same microorganism again then the B cells and antibodies already synthesised for this microorganism will remember that microorganism and will produce a much stronger secondary immune response to fight against microorganism and hence protects body from any disease.
