ANATOMY

Detailed explanation-1: -Passive Immunity. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system. A newborn baby acquires passive immunity from its mother through the placenta.

Detailed explanation-2: -Secretory immunoglobulin A (IgA) is the main antibody found in breast milk, and it’s considered the most important one.

Detailed explanation-3: -During the last 3 months of pregnancy, antibodies from mothers are passed to their unborn babies through the placenta. This type of immunity is called passive immunity because the baby has been given antibodies rather than making them itself.

Detailed explanation-4: -Conclusions: Breastfeeding may, in addition to the well-known passive protection against infections during lactation, have a unique capacity to stimulate the immune system of the offspring possibly with several long-term positive effects.
