Term | Definition |
Ingestion | taking in of nutrients/food |
mechanical digestion | physical breaking apart of large pieces to small pieces |
chemical digestion | breaks large molecules (polymers) into small molecules (monomers); carbs --> simple sugars proteins --> amino acids lipids --> fatty acids & glycerol |
absorption | transfer of small molecules across CELL membrane |
mouth | site of ingestion; site of mechanical digestion & chemical digestion of carbohydrates/starches |
epiglottis | flap that covers the trachea to prevent food from entering trachea |
esophagus | tube that connects mouth (pharynx) to stomach |
stomach | bag shaped organ; site of mechanical digestion (churning) & chemical digestion to form chyme; beginning of protein digestion |
peristalsis | squeezing action that propels food through the esophagus |
small intestines | absorption of nutrients & chemical digestion |
large intestines | absorption of water |
liver | produces bile and other enzymes, detoxifies blood |
gall bladder | stores bile |
pancreas | produces insulin & glucagon for the breakdown of glucose |
rectum | storage place for feces |
anus | sphincter that controls elimination of feces |
chyme | partially digested food found in the stomach |
bolus | small ball of chyme that enters small intestines |
buffer | sodium bicarbonate neutralizes acidic chyme in small intestines |
absorption | transfer of small molecules across CELL membrane |
villi | fingerlike projections found in small intestines that increase surface area for absorption |
22. amylase | enzyme that breaks down starches; found in saliva (in mouth) |
23. lipase | enzyme that breaks down lipids (in small intestines) |
24. protease | enzyme that breaks down proteins (in stomach) |
25. bile | emulsifies lipids (breaks lipids to small particles); stored in gall bladder --> small intestines |
26. pepsin | enzyme that breaks down proteins (in stomach) |
27. pepsinogen | enzyme that breaks down proteins (in stomach) |
