Hint: Cords of billroth are found in the organ which is also known as the graveyard of red blood cells (RBCs). This organ is also involved in generation immune responses against pathogens in the body.

Complete answer:
-In the red pulp of the spleen between the sinusoids, consisting of fibrils and connective tissue cells with a large population of monocytes and macrophages, the Billroth Cords (also known as splenic cords or red pulp cords) are located. Before joining the sinusoids, erythrocytes migrate through the Billroth cords.
-A bottleneck can be seen as the passage through the sinusoids, where erythrocytes need to be versatile in order to move through.
-The spleen parenchyma is composed of white pulp and red pulp.
-The red pulp is reticular tissue, with lymphoid cell splenic cords (Billroth cords) located between the sinusoids.
-The red pulp includes set and roaming macrophages, monocytes,
lymphocytes, plasma cells, platelets, and granulocytes besides reticular cells.
-The white pulp comprises lymphatic tissue arranged around central arteries in sheaths and lymphoid nodules attached to the sheaths.
-A marginal region, consisting of sinuses and loose lymphoid tissue, lies between the white pulp and red pulp.
-There are few lymphocytes in this region, but there are several macrophages showing active phagocytosis. This region is home to blood-borne antigens and thus plays a major role in the spleen's immunologic function.
-The marginal zone is also the site of entry into the spleen for T and B cells until their particular splenic location is separated.
So, the correct answer is ‘Spleen’.

Note: -They are named after the Austrian physician, Theodor Billroth.
-A site for antigen-dependent lymphocyte responses and protection against blood-borne pathogens is the young adult spleen.
