The lymphatic system houses which immune cells?

Explanation:
The lymphatic system is a key hub for immune cells, especially lymphocytes. These white blood cells—including B cells and T cells—reside in lymphoid tissues such as lymph nodes, the spleen, thymus, and tonsils, where they are activated, proliferate, and coordinate specific immune responses. Lymphocytes circulate through lymph and blood, patrolling for pathogens and coordinating defenses, which is why this system is closely tied to adaptive immunity. The other options aren’t immune cells: erythrocytes are red blood cells that carry oxygen, platelets help with blood clotting, and chondrocytes are cartilage cells.
