Describe the difference between natural and acquired immunity.
What will be an ideal response?
1. Natural immunity—Also called innate immunity. It is not specific at attacking a particular
pathogen and it requires no previous exposure to an antigen; an example is the macrophage.
2. Acquired immunity—Response to a specific antigen/pathogen; passive acquired immunity
occurs when a person receives a protective substance produced by another human or animal such
as antibodies traveling from a mother to a fetus. Active acquired immunity develops following
direct exposure to the pathogenic agent such as having the chickenpox or receiving a
vaccination.
