Select the incorrect statement with respect to acquired immunity.
  1. Anamnestic response is elicited on subsequent encounters with the same pathogen
  2. Anamnestic response is due to memory of first encounter
  3. Acquired immunity is non-specific type of defense present at the time of birth

Solution

There are two main types of immunity in human body:

  1. Innate immunity is the non-specific immunity present at the time of birth. This works on physical, physiological, cytological and chemical barriers.
  2. Acquired immunity is the adaptive or specific immunity which a person develops during his/her lifetime. This works by B-cell and T-cells of the body.
