Portage Learning A&P 1 Module 3
1. What are the two main groups of digestive system?:
1. alimentary canal
2.accessory digestive organs
2. What is the alimentary canal?: Continuous muscular digestive tube that runs from
the mouth to the anus
3. What are parts of the alimentary canal?: mouth, pharynx, esophagus, stomach, small
intestine, large intestine, and anus
4. What are the accessory organs of the digestive system?: teeth, tongue, gall bladder,
salivary glands, liver, pancreas
5. The mouth is made of what structures?: Lips (opening) tongue (floor) cheeks (walls)
hard and soft palate
(roof) Uvula (posterior
border)
6. What is the lingual frenulum?: Fold of mucous membrane that secures the tongue
to the floor of the mouth
7. What are the tongues attachment points?: hyoid bone
mandible
lingual
frenulum
8. What is mastication?: mechanical process of breaking down food with teeth
9. what is amalyse?: Enzyme secreted by salivary glands that breaks down starches
10. How many teeth are in the human mouth?: 32
11. What is the purpose of each tooth?: incisor = biting canine = tearing premolar =
grinding flat molar = crushing
12. Three main parts of the teeth: Root - the largest portion of the teeth
Neck- portion contained in upper portion of gingiva
Crown- visible portion of tooth above gum line
13. What is Dentin?: bone like substance of the tooth
14. What is Enamel?: hard connective tissue which protects rest of the tooth
15. What is the purpose of the tongue?: grips food and constantly repositions between
teeth as well as pushes bolus to pharynx
1/6
, 16 What types of papillae contain taste buds?: circumvallate, fungiform
17. Where are taste buds found?: tongue, surface of mouth, wall of pharynx
18. What is purpose of pharynx: throat connects the mouth to the esophagus
19. purpose of two skeletal muscles in pharynx?: circumferential (outer layer)
longitudinal (inner layer)
contract alternatively causing peristalsis, squeezing food to esophagus
20. What is the purpose of esophagus?: transports food from the mouth to the stomach
21. What is name of sphincter that separates esophagus and stomach?: cardiac
22. Four layers of the alimentary canal: mucosa- secretes mucus to move bolus
submucosa- contains blood, lymph nodes, and nerve endings
muscularus externa- muscles that contract and move bolus
through GI tract serosa- makes serous fluid to keep GI tract
lubricated
23. Layers of muscularus externa: Inner- circumferential
Outer- longitudinal
Oblique- only in stomach, helps intensify peristalsis for stomach digestion
24. What is the purpose of the stomach?: Temporary storage are for food, digests and
breaks down food w/ combination of muscles and digestive juices
25. How does stomach attach?: Lesser omentum- lesser curvature of stomach to liver
greater omentum- attaches to greater curvature of stomach and posterior wall of
abdomen, hangs like apron
26. Name the two curvatures of the stomach: lesser curvature (concave) greater
curvature (convex)
27. Four parts of the stomach: Carida- food enters from esophagus Fundus- dome
shaped top under diaphragm body- wider midportion
pyloric- funnel shaped part at the bottom
28. Where is stomach located: left side of the abdomen, below the diaphragm. Back
word C shaped
29. What is rugae?: folds in stomach that allow it to expand when full
30. A thick layer of mucus coats stomach to prevent __________ from eroding at
stomach lining: Pepsin
