The immune system is one of the most complex systems of our body. When our body is being faced with different conditions, it needs to protect itself from different dangers. It should be able to Identify and neutralize the foreign elements in the most appropriate manner. The main cells that are responsible for defending the body are leukocytes. In some people, the immune system may have certain gaps.
