  1. Specificity: It can produce a specific antibody or T-lymphocyte against a particular antigen/pathogen.
  2. Diversity: It can recognize a vast variety of diversity pathogens or foreign molecules.
  3. Discrimination between self and non-self: It differentiates between the own body (self) and foreign (non-self) molecules.
  4. Memory: When the immune system encounters a specific foreign agent for the first time, it generates an immune response and eliminates the invader. This is called a first encounter. The immune system retains the memory of the first encounter. As a result, a second encounter with the same pathogen brings about quicker.
