Question

Quizplus · Accepted Answer

Absorbed lipids are condensed with glycerol in the epithelial cells into triacylglycerols and re-packaged into chylomicrons that are initially transported by the lymphatic system. Chylomicrons are too large to enter the bloodstream directly, so they enter the lymphatic vessels and eventually enter the bloodstream via the thoracic duct. VLDL and LDL are not involved in the absorption and transport of dietary lipids. Phospholipids are a minor component of chylomicrons and are not packaged into VLDL. The portal system transports most nutrients from the gastrointestinal tract to the liver, but chylomicrons bypass this system by entering the lymphatic vessels.
