Which of the following statements regarding secondary lymphoid organs is incorrect?
Options
- APeyer's patches of the large intestine act as secondary lymphoid organs.
- BSecondary lymphoid organs provide the sites for interaction of lymphocytes with the antigen.
- CAfter interaction with antigens, lymphocytes proliferate to become effector cells.
- DLymph nodes serve to trap the micro-organisms which happen to get into the lymph and tissue fluid.
Correct answer
A. Peyer's patches of the large intestine act as secondary lymphoid organs.
Step-by-step solution
Peyer's patches are located in the small intestine, not the large intestine. Therefore, the statement identifying them as part of the large intestine is incorrect. Secondary lymphoid organs (such as the spleen, lymph nodes, tonsils, Peyer's patches of small intestine and appendix) provide the sites for interaction of lymphocytes with the antigen, which then proliferate to become effector cells. Lymph nodes are small solid structures located at different points along the lymphatic system that serve to trap the micro
