Vedclass · Answer

(B) When the body encounters a pathogen for the first time,it produces a response called the $Primary$ $response$.$Primary$ $response$ is of low intensity.- During this process,memory cells are formed.- These memory cells are stored in the spleen and lymph nodes.When the body encounters the same pathogen subsequently,the immune system recognizes it and elicits a $Secondary$ $response$ (also known as an $Anamnestic$ $response$).$Secondary$ $response$ is of much higher intensity due to the rapid proliferation of these memory cells.
