Question | Answer |
---|---|

rhythmic contractions of the tubular organs. in the GI tract, peristalsis moves the contents through at different rates; stomach, 0.5-2 hours; small intestine, 2 to 6 hours; and colon, 6 to 72 hours. peri - means surrounding; stalks is constriction | peristalsis |
throat, the common passageway for food from the mouth and for air from the hose | pharynx |
large vein bringing blood to the liver from the intestines | portal vein |
enzyme that digests protein | protease |
soft tissue within a tooth, containing nerves and blood vessels | pulp |
ring of muscle at the end of the stomach, near the duodenum. from the greek pyloros, meaning gatekeeper. it is normally closed, but opens when a wave of peristalsis passes over it | pyloric sphincter |
distal region of the stomach, opening to the duodenum | pylorus |
last section of the large intestine, connecting the end of the colon and the anus | rectum |
ridges on the hard palate and the wall of the stomach | rugae |
digestive juice produced by salivary glands. saliva contains the enzyme amylase, which begins the digestion of starch to sugar | saliva |
parotid, sublingual, and submandibular glands | salivary glands |
fourth and last, S-shaped segment of the colon, just before the rectum; empties into the rectum | sigmoid colon |
circular ring of muscle that constricts a passage or closes a natural opening | spinchter |
muscular organ that receives food from the esophagus. the stomach's parts are the fundus (proximal section), body (middle section), and Antrum (distal section) | stomach |
fat molecules composed of three parts fatty acids and one part glycerol. triglycerides )fats) are a subgroup of lipids. another type of lipid is cholesterol | triglycerides |
