Mature chylomicrons

Mature chylomicrons are released through the basolateral membrane of enterocytes (via the secretory pathway) into lacteals, lymphatic capillaries in the villi of the small intestine. Lymph that contains chylomicrons (and other emulsified fats) is referred to as chyle. The lymphatic circulation carries chyle to the lymphatic ducts before it enters the venous return of the systemic circulation via subclavian veins. From here, chylomicrons can supply tissue throughout the body with fat absorbed from the diet. Because they enter the bloodstream in this way, digested lipids (in the form of chylomicrons) bypass the hepatic portal system and thus avoid first pass metabolism, unlike digested carbohydrates (in the form of monosaccharides) and proteins (in the form of amino acids).
