There are two main types of lymphocytes:

* T lymphocytes (T cells): These cells mature in the thymus and play a key role in cell-mediated immunity. They directly attack infected or cancerous cells.

* B lymphocytes (B cells): These cells mature in the bone marrow and are responsible for humoral immunity. They produce antibodies that target specific antigens.

While the lymphatic system is primarily responsible for producing lymphocytes, it also contains other cell types that contribute to its functions, such as:

* Macrophages: These cells engulf and destroy pathogens and cellular debris.

* Dendritic cells: These cells present antigens to T cells, initiating an immune response.

* Natural killer (NK) cells: These cells kill infected or cancerous cells without the need for prior sensitization.
