Well im not sure about large intestine, but. Since Vit K is lipid soluble and as all lipid soluble stuff(fats that we ingest) go through lymphatics first and then drain to the Circulation through Thoracic Duct.

of course the absorption of vitamin k in small intestine is not an unusual event . but in the large intestine it is absorbed into the blood vessels . This is very unusual because fats and all other fat soluble vitamins are absorbed through the lymphatic system . why the absorption of this vitamin in the large intestine is through blood vessels instead of lymph?
