Afferent lymphatic vessels vs efferent lymphatic vessels: direction?

Lymph nodes are structured to receive fluid from the surrounding tissues and then drain it away after taking a look at the immune cells inside. Lymphatic fluid enters the node through afferent lymphatic vessels on the outer side, moves through the subcapsular and trabecular sinuses where immune cells screen it, and finally exits through efferent lymphatic vessels at the hilum. This setup creates a one-way path that maximizes filtration and antigen exposure before the fluid leaves the node. So, afferent vessels bring lymph to the lymph node and efferent vessels carry it away.
