Spleen7
Importantly, while lymph nodes can be thought of as the draining secondary lymphoid organs of the respective anatomic compartments via afferent lymphatics (ie the lung drains into the mediastinum), the spleen can be thought of as the primary draining secondary lymphoid organ of the systemic circulatory system with the afferent inflow occurring via the splenic artery instead of afferent lymphatics.

An enlarged spleen can be the cause of hypersplenism, that is, sequestration and excessive destruction of blood cells (usually all, although it is limited to 1 or 2 cell lines) by splenic macrophages. (acnm-online-pharmacy-usa-store.com)
