PATHOLOGY

Detailed explanation-1: -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: -A type of immunity that occurs when a person is given antibodies rather than making them through his or her own immune system. For example, passive immunity occurs when a baby receives a mother’s antibodies through the placenta or breast milk.

Detailed explanation-3: -Passive immunity can occur naturally, such as when an infant receives a mother’s antibodies through the placenta or breast milk, or artificially, such as when a person receives antibodies in the form of an injection (gamma globulin injection).

Detailed explanation-4: -A type of immunity that develops when a person’s immune system responds to a foreign substance or microorganism, or that occurs after a person receives antibodies from another source. The two types of acquired immunity are adaptive and passive.

Detailed explanation-5: -In passive immunization a person receives antibodies or lymphocytes that have been produced by another individual’s immune system; in active immunization the individual’s own immune system is stimulated to produce antibodies and lymphocytes.
