Verified step by step guidance

Understand the concept of natural immunity: Natural immunity refers to the protection that an individual acquires without medical intervention. It can be either active or passive.

Differentiate between active and passive immunity: Active immunity involves the body's direct response to an unknown pathogen, while passive immunity is acquired through the transfer of antibodies from another source.

Identify examples of passive natural immunity: Passive natural immunity occurs when antibodies are transferred from one individual to another naturally, such as from mother to child.

Recognize the role of breast milk in passive immunity: Breast milk contains antibodies, particularly IgA, which are passed from the mother to the child, providing the child with temporary immunity against certain infections.

Conclude that the transfer of antibodies through breast milk is an example of natural immunity acquired passively, as it involves the natural transfer of antibodies without medical intervention.
