Mucosa-Associated Lymphoid Tissue (MALT) — NEET Biology
✅ Asked in NEET 2024There is lymphoid tissue also located within the lining of the major tracts (respiratory, digestive and urogenital tracts) called mucosa-associated lymphoid tissue (MALT). It constitutes about 50 per cent of the lymphoid tissue in human body.
MALT is lymphoid tissue embedded in the linings of respiratory, digestive, and urogenital tracts, representing about 50% of all lymphoid tissue in the human body. NETA tests students' knowledge of MALT's location and its quantitative contribution to total lymphoid tissue. Students often confuse MALT with other lymphoid organs like thymus or spleen, or forget that it constitutes exactly 50% of lymphoid tissue. Remember: MALT is distributed along major body tracts (not centralized), and its large proportion makes it crucial for mucosal immunity at entry points where pathogens commonly invade.
