Verified step by step guidance

Understand the anatomy of a lymph node: A lymph node is a small, bean-shaped structure that is part of the lymphatic system. It filters lymph and houses immune cells. Key components include the cortex, medulla, and lymphatic sinuses.

Identify the correct component: The cortex is a region of the lymph node that contains densely packed lymphocytes, primarily B cells, organized into follicles. It plays a critical role in immune response.

Eliminate unrelated options: Alveolus is a structure found in the lungs, responsible for gas exchange. Islets of Langerhans are clusters of cells in the pancreas that regulate blood sugar. Nephron is the functional unit of the kidney involved in filtration and urine production.

Focus on the correct answer: The cortex is the only option that is anatomically part of a lymph node. It is involved in filtering lymph and initiating immune responses.

Review the lymph node structure: Reinforce the understanding of the lymph node's anatomy and function, emphasizing the role of the cortex in housing immune cells and supporting lymph filtration.
