Activity 4: Tracing Digestive Pathways 1. Amylase converts starch into and 2. Proteins are chemically broken down into large polypeptides by large polypeptides are broken down into small polypeptides by and and small polypeptides are broken down into amino enzymes in the cells lining the villus. acids by and 3. Amino acids enter the capillary at the villus through are transported to the superior mesenteric vein, which fuses with the vein to form the vein, which transports blood to the liver. 4. When fatty chyme enters the duodenum, the release of the hormone triggers smooth muscle contraction in the causing the release of bile. Bile travels first through the duct, then into the duct before entering the duodenum.
