Verified step by step guidance1
Understand the structure of a lymph node: Lymph nodes have a convex side where lymph enters and a concave side called the hilum where lymph exits.
Identify the types of lymphatic vessels: Afferent lymphatic vessels bring lymph into the lymph node, while efferent lymphatic vessels carry lymph away from the node.
Trace the path of lymph through the lymph node: Lymph enters through the afferent lymphatic vessels on the convex side.
Follow the flow of lymph within the node: Once inside, lymph moves through the cortex, which is the outer part of the lymph node, and then into the medulla, the inner part.
Determine how lymph exits the node: Lymph exits the node at the hilum via the efferent lymphatic vessels.
