Explanation:
Detailed explanation-1: -The thymus gland is the primary lymphoid organ for lymphocyte development. The red bone marrow produces B-lymphocytes (B cells) and T lymphocytes (T cells). B cells achieve immunocompetence (ability to recognize a specific antigen) in bone marrow. T cells migrate to the thymus gland, where they become immunocompetent.
Detailed explanation-2: -T cells migrate from the bone marrow to the thymus, a small gland located in the neck. Here, they mature and differentiate into different types of T cells, such as CD8+ T cells and CD4+ T cells.
