Nutrition and Digestion In Humans
| Question | Answer |
|---|---|
| Study of nutrients and how they are used by the body | nutrition |
| Begins the breakdown of starch into maltose | Saliva/salivary glands |
| Physical digestion: grinding and tearing occurs in the ... | mouth |
| Waves of muscle contraction that push food through digestive tract | Peristalsis |
| Continues physical breakup of food, begins breaking up protein into polypeptides, and acts as a storage area for food before releasing into intestine | Stomach |
| Food becomes ____, an acidic liquid mixture, after churning | chyme |
| Completes chemical digestion of food | Small intestine |
| ____ produces bile | Liver |
| Bile is stored in the ____, which later empties it into the small intestine via the common bile duct | Gallbladder |
| ___ ___ break up fats into small globules | Bile salts |
| fats become small globules | emulsification |
| Secretes digestive fluids into the small intestine | pancreas |
| Enzyme in mouth: starch > maltose | Salivary amylase |
| Enzyme in stomach: proteins > polypeptides | Pepsin |
| Enzyme in small intestine: stach > disaccharides | Pancreatic amylase |
| Enzyme in S.I.: proteins > polypeptides | Proteases |
| E in S.I.: polypeptides > amino acides | Peptidases |
| E in S.I.: fats > fatty acids and glycerol | Lipases |
| Es in S.I.: disaccharides > monosaccharides | maltase, lactase, sucrase |
| Fingerlike projections that increase intestine's absorptive area | villi |
| Monitors glucose level by converting excess glucose to glycogen | liver |
| Regulates levels of amino acids | liver |
| absorbs water to make poop | large intestine |
| Friendly bacteria live here | large intestine |
