Which of the Following is NOT a Mucosa-Associated Lymphoid Tissue

Question

Which of the following is NOT a Mucosa-Associated Lymphoid Tissue (MALT)?
A) appendix
B) tonsil
C) thymus
D) intestines

Accepted Answer

The thymus is not considered a Mucosa-Associated Lymphoid Tissue (MALT) as it is not directly involved in the immune response to mucosal pathogens. The other options (appendix, tonsil, and intestines) are all considered MALT as they contain immune cells that help defend against pathogens that enter the body through mucosa.
