Q.124) After maturation, in primary lymphoid organs, the lymphocytes migrate for interaction with antigens to secondary lymphoid organ(s) / tissue(s) like:
A. thymus
B. bone marrow
C. spleen
D. lymph nodes
E. Peyer's patches
Choose the correct answer from the options given below
A) C, D, E only
B) B, C, D only
C) A, B, C only
D) E, A, B only
After maturing in the primary lymphoid organs (bone marrow and thymus), lymphocytes move to secondary lymphoid organs like the spleen, lymph nodes, and Peyer’s patches. These are the sites where they encounter antigens and start immune responses. So, the correct secondary lymphoid tissues here are the spleen, lymph nodes, and Peyer’s patches.
Hence, option(1) is correct.
