검증된 단계별 안내1
Understand the structure of a lymph node: Lymph nodes are small, bean-shaped structures that filter lymph fluid. They contain sinuses and vessels that guide the flow of lymph.
Identify the entry point: Lymph enters the lymph node through afferent lymphatic vessels. These vessels bring lymph fluid into the node.
Trace the path through the sinuses: Once inside, lymph flows into the subcapsular sinus, which is located just beneath the capsule of the lymph node.
Follow the lymph through the node: From the subcapsular sinus, lymph moves into the trabecular sinus, which extends inward from the capsule, and then into the medullary sinus, located in the central part of the node.
Determine the exit point: After passing through the medullary sinus, lymph exits the lymph node via efferent lymphatic vessels, which carry the filtered lymph away from the node.
