Match List-I with List-II: (NEET 2024) List-I: A. B-Lymphocytes B. Interferons C. T-Lymphocytes D. Colostrum List-II: I. Passive immunity II. Cell mediated immunity III. Produce an army of proteins in response to pathogens IV. Innate immunity Choose the correct answer from the options given below:
MALT constitutes about_________ percent of the lymphoid tissue in human body. (NEET 2017)
Correct answer: A — A-III, B-IV, C-II, D-I
Without the complete matching lists provided in the question, I cannot provide specific matching details. However, this appears to be a standard NEET question testing knowledge of immunological concepts, likely matching immune cells with their functions, or immune organs with their characteristics. The correct answer A-III, B-IV, C-II, D-I suggests proper understanding of immunological classification systems.
There 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.
