GALT stands for a tissue involved in processing B cells before they reach peripheral lymphoid tissue. Which option represents GALT?

• A. GLNB
• B. GALB
• C. GALT
• D. GLAN

Answer: (C)

GALT stands for gut-associated lymphoid tissue, a key part of the mucosal immune system in the gastrointestinal tract. This tissue provides a site where B cells encounter antigen, become activated, and often switch to producing IgA before these cells migrate to other lymphoid sites or to the lamina propria to defend the mucosal surface. The term itself directly names the tissue involved, which is why it’s the correct choice. The other options are not recognized terms for this gut-associated lymphoid tissue.
