<P> Chylomicrons are formed in the endoplasmic reticulum in the absorptive cells ( enterocytes ) of the small intestine . The villi , lined with the microvilli of the brush border , provide a lot of surface area for absorption . Newly formed chylomicrons are secreted through the basolateral membrane into the lacteals , where they join lymph to become chyle . The lymphatic vessels carry the chyle to the venous return of the systemic circulation . From there the chylomicrons supply the tissue with fat absorbed from the diet . Thus , unlike the saccharides and amino acids that digestion liberates from the carbohydrates and proteins of the diet ( respectively ) , the lipids from the diet bypass the hepatic portal system , meaning the liver does not get `` first crack '' at them . </P>
