Answered by Examlex AI CopilotNatural immunity refers to the immunity that is naturally acquired by the body in response to exposure to a pathogen. This can occur through previous infection or through the transfer of antibodies from mother to baby during pregnancy or breastfeeding.
Artificial immunity, on the other hand, is immunity that is acquired through medical intervention, such as vaccination. This can involve the administration of a weakened or inactivated form of a pathogen to stimulate the body's immune response and create immunity without causing the disease.
Active immunity refers to the immunity that is developed by the body in response to an antigen, either through natural exposure to the pathogen or through vaccination. This type of immunity involves the production of antibodies and memory cells that provide long-term protection against the specific pathogen.
Passive immunity, on the other hand, is the transfer of pre-formed antibodies from one individual to another. This can occur naturally, such as the transfer of antibodies from mother to baby during pregnancy or breastfeeding, or artificially through the administration of antibodies obtained from another individual or animal.
An example of natural passive immunity is the transfer of maternal antibodies to a baby through breastfeeding. When a mother breastfeeds her baby, she passes on antibodies that she has developed in response to various pathogens, providing the baby with temporary protection until their own immune system matures.
Match each type of specific immunity with its description or example.
