What are medullary cords?

Where is the largest collection of lymph nodes?
Spleen: This largest lymphatic organ is located on your left side under your ribs and above your stomach. The spleen filters and stores blood and produces white blood cells that fight infection or disease.
What are splenic cords?
The cords of Billroth (splenic cords) are the cellular aggregations supported by the reticular connective tissue. They appear as stripes and consist of of macrophages, plasmocytes and blood cells. Splenic sinusoids are found between the cords of Billroth.
What is included in the GALT?
Gut-associated lymphoid tissue (GALT) includes Peyer’s patches, the appendix, and scattered solitary or isolated lymphoid follicles (ILFs). Peyer’s patches occur mainly in the ileum (less frequently in the jejunum) and consist of at least five aggregated lymphoid follicles (Fig.
