Explanation:
Detailed explanation-1: -Thymus produces progenitor cells that develop into T-cells. These T-cells help the body fight against infections. They also aid in the growth of other organs in the immune system.
Detailed explanation-2: -T lymphocytes develop from a common lymphoid progenitor in the bone marrow that also gives rise to B lymphocytes, but those progeny destined to give rise to T cells leave the bone marrow and migrate to the thymus (see Fig. 7.2). This is the reason they are called thymus-dependent (T) lymphocytes or T cells.
