 How to work immune system?

Ans- Immunity system is combination of immune cells and proteins. some immune cells is work non stop like Natural Killer ,Macrophages and  some work specific like T-cell and B-cell and proteins work similarly.

          When the body sense invader substances the immune system works to recognize the invader and how to get rid of them.

Natural killer(NK) kills only the invader substances like bacteria or virus and macrophages kills and identify the bacteria or virus and this cell informs to the T-cells.

T-cells activate the B-cells and B-cells prepare the antibody and antibody is a protein which is seen in Y shape. 

Finally when antibody is prepared then we say that we are immune that means we are immune from particular virus or bacteria and inside the immune system has a memory cell which is called B-cells and B-cells convert in memory cell and to keep the picture image for future that means if our body is infected again then fast antibody is prepared and to quick response. so you are infected once from bacteria or virus then second times is less effect on our body and that is called immune response.
