Question

1. which type of immunity is provided by colostrum obtained from the mothers first milk? a passively acquired immunity provided by immunoglobulin injections. b artificially acquired passive immunity. c naturally acquired passive immunity. d naturally acquired active immunity. check it skip

Explanation:

Colostrum is the first milk produced by the mother after childbirth. It contains antibodies (immunoglobulins) that are transferred to the infant. Passive immunity involves the transfer of antibodies (rather than the infant's own immune system actively producing them). Since this transfer occurs naturally (through breastfeeding), it is naturally acquired passive immunity.

• Option a: Immunoglobulin injections are artificial, not related to colostrum.
• Option b: Artificially acquired passive immunity would involve medical interventions like injections, not natural feeding.
• Option d: Active immunity would require the infant's immune system to be stimulated (e.g., by an infection or vaccine), which is not the case here as antibodies are transferred.

Answer:

C. Naturally acquired passive immunity.
