The Cords of Billroth (also known as splenic cords or red pulp cords) are found 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. They contain half the body's monocytes as a reserve that after tissue injury can move in and aid wound healing.^[1]

[edit] Eponym

They are named for Theodor Billroth, Austrian surgeon.^[2]
