- chewing stimulates secretion of saliva from salivary glands

- salivary amylase breaks down starch into shorter polysaccharides and maltose

- no absorption occurs

- salivary glands produce enzyme lingual lipase that digests some triglycerides

- little lipid digestion occurs

- chewing increases surface area

- no absorption or enzymatic digestion occurs

- salivary amylase is destroyed

- no digestion or absorption occurs

- food mixes with gastric juices

- arrives intact

- mixes with gastric juices and broken into droplets

- gastric lipase digests some triglycerides

- little digestion occurs

- denaturation occurs by hydrochloric acid

- pepsin is activated to break protein into single amino acids and smaller polypeptides

- pancreatic amylase is secreted into small intestine

- release lipid-digesting enzymes to small intestine

- release proteases to small intestine

- contracts due to hormone CCK

- release bile into small intestine

- pancreatic amylase breaks down remaining starch into maltose

- specific enzymes break down disaccharides into monosaccharides

- all monosaccharides are absorbed and enter blood stream

- broken into smaller droplets by bile

- lipid-digesting enzymes break triglycerides into monoglycerides and fatty acids

- lipid-digesting enzymes break dietary cholesterol esters and phospholipids into their components

-micelles transport lipid digetsion products to the enterocytes for absorption

- chylomicrons transport the longer chain fatty acids and monoglycerides through lymphatic system until thoracic duct and enter bloodstream bypassing the liver carrying triglycerides through bloodstream directly to body's cells to be used for energy or to be stored

- proteases are secreted to digest polypeptides into smaller units

- peptidases on the surface of cells complete breakdown of all polypeptides into single amino acids

- where monosaccharides travel to via bloodstream, then to cells to provide energy

- excess glucose is stored as glycogen in liver

- where amino acids are transported to via blood stream then sent to cells as needed

- where polysaccharides pass to

- bacteria ferment some undigested polysaccharides

- remaining undigested polysaccharides are excreted in feces
