Document Summary

Teeth crush large pcs of food into smaller ones. Fluids dissolve the food so the tongue can taste it. Taste buds detect one, or a combination, of the four basic taste sensations: sweet, sour, bitter, and salty. 5th sensation: unami = savoury detected by monosodium glutamate. Food swallowed epiglottis closes to block off air pathway pharynx (food pathway) food bolus esophagus: esophagus. Upper sphincter opens: bolus slides down esophagus and passes thru a hole in the diaphragm to the stomach (challenge 2) Lower sphincter closes: at entrance to stomach; prevents the bolus from slipping back into the esophagus (challenge 3: stomach. Stomach slowly transfers bolus from upper to lower portion of the stomach adding juices to it to create chyme. Chyme: the semiliquid mass of partly digested food: small intestine. Chyme bypasses common bile duct opening (challenge 4) 3 sections of si: duodenum jejunum ileum. Anything remaining must go thru another sphincter at the beginning of the li (the cecum)
