Match each type of immunity in the numbered list with its associated example from the lettered list.
1. ___ Artificially acquired passive immunotherapy
2. ___ Naturally acquired active immunity
3. ___ Naturally acquired passive immunity
4. ___ Artificially acquired active immunity
A. Production of IgE in response to pollen
B. Acquisition of maternal antibodies in breast milk
C. Administration of tetanus toxoid
D. Administration of antitoxin

Verified step by step guidance

1. Understand the definitions of each type of immunity: 1) Artificially acquired passive immunity involves receiving antibodies from an external source, 2) Naturally acquired active immunity occurs when the body produces its own antibodies after exposure to an antigen naturally, 3) Naturally acquired passive immunity is the transfer of antibodies from mother to child naturally, and 4) Artificially acquired active immunity involves stimulating the body to produce antibodies through vaccination.
2. Match 'Artificially acquired passive immunotherapy' with the example where antibodies are given directly to a person, such as the administration of antitoxin (Example D).
3. Match 'Naturally acquired active immunity' with the example where the body naturally produces antibodies in response to an environmental antigen, such as the production of IgE in response to pollen (Example A).
4. Match 'Naturally acquired passive immunity' with the example where antibodies are naturally transferred from mother to child, such as acquisition of maternal antibodies in breast milk (Example B).
5. Match 'Artificially acquired active immunity' with the example where a vaccine or toxoid is administered to stimulate antibody production, such as administration of tetanus toxoid (Example C).

Key Concepts

Types of Immunity

Immunity can be classified as active or passive, and as naturally or artificially acquired. Active immunity involves the body producing its own antibodies, while passive immunity involves receiving antibodies from another source. Natural acquisition occurs through everyday life, whereas artificial acquisition involves medical intervention.

Active Immunity

Active immunity results when the immune system is stimulated to produce antibodies and memory cells after exposure to an antigen. Naturally acquired active immunity happens through infection, while artificially acquired active immunity occurs via vaccination, such as receiving a toxoid to trigger antibody production.

Passive Immunity

Passive immunity involves the direct transfer of antibodies from one individual to another, providing immediate but temporary protection. Naturally acquired passive immunity occurs when maternal antibodies are passed to a baby through breast milk, whereas artificially acquired passive immunity involves receiving antibodies through treatments like antitoxins.
