Which of the following is most related to the placental transfer of antibodies from the mother to the fetus?
Naturally acquired active immunity
Artificially acquired active immunity
Artificially acquired passive immunity
Naturally acquired passive immunity
The Correct Answer is D
A. Naturally acquired active immunity occurs when the body is exposed to a pathogen, and the immune system produces its own antibodies in response. This type of immunity is not related to the transfer of antibodies from mother to fetus.
B. Artificially acquired active immunity involves vaccination, where the immune system is exposed to a weakened or inactivated pathogen to stimulate an immune response. This does not involve the transfer of antibodies from the mother.
C. Artificially acquired passive immunity involves the transfer of antibodies through medical interventions, such as antibody injections or serum treatments. While this involves passive immunity, it is not naturally occurring, nor is it related to placental transfer.
D. Naturally acquired passive immunity refers to the transfer of antibodies from mother to fetus through the placenta. These antibodies provide temporary protection to the newborn against infections, and this process is a natural example of passive immunity.

Correct Answer is B
Explanation
A. GALT (Gut-Associated Lymphoid Tissue) refers to lymphoid tissue found in the gastrointestinal tract, not a part of the lymph node.
B. The hilum is the indented area of a lymph node where blood vessels, nerves, and efferent lymphatic vessels (which carry lymph out of the node) exit the node.
C. Buboes are swollen lymph nodes, often a sign of infection like bubonic plague, not the area where vessels exit the lymph node.
D. Filariae are parasitic worms that can cause lymphatic filariasis, but they are not related to the structure of a lymph node.
Correct Answer is C
Explanation
A. They have thin walls – Lymphatic vessels have thin walls, similar to veins, which allow for the passage of lymph.
B. They can contract to propel lymph – Lymphatic vessels do have the ability to contract, aided by smooth muscle and valves, which helps propel lymph in the right direction.
C. They transport lymph to the tissues – This statement is incorrect. Lymphatic vessels carry lymph away from the tissues (not to the tissues) and toward lymph nodes and eventually to the bloodstream.
D. They are blind-ended – Lymphatic capillaries are indeed blind-ended, meaning they begin as closed-ended tubes that absorb interstitial fluid from tissues.
