questions with correct answers


mechanical digestion - CORRECT ANSWER✔✔-Part of digestion that uses
| | | | | | | | |


movement and muscles to break down food into smaller pieces
| | | | | | | | |




digestion - CORRECT ANSWER✔✔-breaking down nutrients into small, soluble
| | | | | | | | |


molecules that can be absorbed into the blood
| | | | | | |




chemical digestion - CORRECT ANSWER✔✔-the digestion process in which
| | | | | | | | |


enzymes are used to break foods into their smaller chemical buiding blocks
| | | | | | | | | | |




occurs via hydrolysis
| |




hydrolysis - CORRECT ANSWER✔✔-A chemical process that lyses, or splits,
| | | | | | | | | |


molecules by the addition of water; an essential process in digestion.
| | | | | | | | | |




enzymes - CORRECT ANSWER✔✔-molecules, usually proteins or nucleic acids,
| | | | | | | | |


that act as catalysts in biochemical reactions
| | | | | |




used in chemical reactions
| | |




humans digestion tube extends from - CORRECT ANSWER✔✔-mouth to anus
| | | | | | | | |




called alimentary canal
| |

,anus - CORRECT ANSWER✔✔-A muscular opening at the end of the rectum
| | | | | | | | | | | |


through which waste material is eliminated from the body
| | | | | | | |




alimentary canal - CORRECT ANSWER✔✔-Also known as the gastrointestinal (GI)
| | | | | | | | | |


tract of the digestive tract, the alimentary canal is the long muscular "tube" that
| | | | | | | | | | | | | |


includes the mouth esophagus, somatch, small intesitne, and large intestine.
| | | | | | | | |




|carries out stages of digestive process (mechanical and chemical digestion and
| | | | | | | | | | |


absorb ion) |




accessory organs - CORRECT ANSWER✔✔-In the GI tract, organs that play a role
| | | | | | | | | | | | |


in digestion but not directly part of the alimentary canal.
| | | | | | | | | |




These include the liver, the gallbladder, the pancreas
| | | | | | |




what takes place in the mouth? - CORRECT ANSWER✔✔-mechanical digestion
| | | | | | | | |




saliva is released from salivary glands to breakdown carbs
| | | | | | | |




salivary glands - CORRECT ANSWER✔✔-three pairs of exocrine glands in the
| | | | | | | | | | |


mouth that secrete saliva
| | |




saliva - CORRECT ANSWER✔✔-contain amylase
| | | |




amylase - CORRECT ANSWER✔✔-enzyme in saliva that breaks the chemical bonds
| | | | | | | | | |


in starches
| |

, pharynx - CORRECT ANSWER✔✔-muscular tube at the end of the gastrovascular
| | | | | | | | | | |


cavity, or throat, that connects the mouth with the rest of the digestive tract and
| | | | | | | | | | | | | | |


serves as a passageway for air and food
| | | | | | |




esophagus - CORRECT ANSWER✔✔-muscular tube that moves food from the
| | | | | | | | | |


pharynx to the stomach
| | |




epiglottis - CORRECT ANSWER✔✔-The flap of tissue that seals off the windpipe
| | | | | | | | | | | |


and prevents food from entering.
| | | |




what takes place in the stomach? - CORRECT ANSWER✔✔-peristalsis
| | | | | | | |




gastric juices help breakdown proteins
| | | | |




chyme is created| |




peristalsis - CORRECT ANSWER✔✔-involuntary waves of muscle contraction that
| | | | | | | | |


keep food moving along in one direction through the digestive system
| | | | | | | | | |




gastric juice - CORRECT ANSWER✔✔-chemically breaksdown proteins
| | | | | | |




acidic (pH of 2)
| | |




mucus - CORRECT ANSWER✔✔-protects stomach wall from acidity of gastric
| | | | | | | | | |


juices


protease - CORRECT ANSWER✔✔-Enzyme that breaks down proteins
| | | | | | |
