Question

Monomeric IgA made by plasma cells in lymph nodes, spleen, and BM; secreted into the bloodstream.

a. True
b. False

Answer 1

False. Monomeric IgA is not made by plasma cells in lymph nodes, spleen, and BM, but is instead secreted into the bloodstream.

Step-by-step explanation:

False. Monomeric IgA is not made by plasma cells in lymph nodes, spleen, and BM. Instead, plasma cells synthesize and secrete dimeric IgA, and to a lesser extent, pentameric IgM. Monomeric IgA is actually secreted into the bloodstream.
