can lymph nodes drain
Lymph is present throughout the body, and circulates through lymphatic vessels. These drain into and from lymph nodes â afferent vessels drain into nodes, and efferent vessels from nodes. When lymph fluid enters a node, it drains into the node just beneath the capsule in a space called the subcapsular sinus. The subcapsular sinus drains into trabecular sinuses and finally into medullary sinuses.
