Which vessels carry lymph into a lymph node?

1. Lymph nodes remove debris and pathogens from the lymph, which is why they are called the filters of the lymph. 2. The major routes into the lymph node are the afferent lymphatic vessels. 3. Cells and fluid leave the node again by a separate set, the efferent lymphatic vessels, so efferent names the exit. 4. High endothelial venules let cells cross in from the blood rather than carrying upstream lymph, and the subcapsular sinus is a space inside the node. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 21 "The Lymphatic and Immune System", section 21.1 Anatomy of the Lymphatic and Immune Systems_
