Specialized lymph formations found in the small intestine mucosa. Together with enzymatic activities in the submucosa, they collect digested fats into stable transport bubbles called chylomicrons, and draw them up into the lymph system. There they are gradually leeched into the blood as the lymph passes upwards through the body, the remainder discharged into the venous blood with the lymph...12-24 hours later. Time-Released fat capsules. Fats lower the blood charge and make it sticky, which can interfere with vascular capabilities; the sideways bypassing of the blood in this manner spreads the fats out over long periods. The rest of the digested constituents can happily flow up to the liver through the portal system, unsludged, and the liver itself has little lipid stress to face. If fats are poorly digested in the upper intestinal tract, the floating bubbles are larger, broken down too slowly to be well absorbed into the lymph system, and the portal blood...and liver...get sludged. Ever wonder why a bunch of lousy pizza can give you hemorrhoids the next day? Sludgy portal blood and backed-up venous drainage from the legs is why.
