Which type of immunity is produced by an individual after either natural exposure to the antigen or after immunization against the antigen?

• passive-aquired
• active-aquired
• passive-innate

d. active innate - ANSWER-ANS: B

Rationale; An individual produces active-acquired immunity (active immunity) after natural exposure to an antigen or after immunization, whereas passive-acquired immunity (passive immunity) does not involve the host's immune response at all. The innate immune system, also known as nonspecific immune system and the first line of defense, is composed of the cells and mechanisms that defend the host from infection by other organisms in a nonspecific manner, which means that the cells of the innate system recognize and respond to pathogens in a generic way. 1 / 4

What type of immunity is produced when an immunoglobulin crosses the placenta?

• passive-aquired
• active-aquired
• passive-innate

d. active-innate - ANSWER-ANS: A

Rationale; Passive-acquired immunity (passive immunity) does not involve the host's immune response at all. Rather, passive immunity occurs when preformed antibodies or T lymphocytes are transferred from a donor to the recipient.This transfer can occur naturally, as in the passage of maternal antibodies across the placenta to the fetus, or artificially, as in a clinic using immunotherapy for a specific disease. The remaining options do not produce immunity via immunoglobulin transfer across the placenta.

• Cystic fibrosis is an example of such a condition - ANSWER-
