Critical Thinking
(3) What effect is a before-dinner alcoholic cocktail likely to have on digestion? Why are such beverages inadvisable for persons with ulcers? They are inadvisable because your body will get dehydrated before you eat so it will take your body longer to digest.

(7)Describe the general effects of the parasympathetic and synpathetic impulses on the alimentary canal? Parasympathetic increases the activities of the digestive system, Sympathetic is the opposite.
(12)Describe the structure of a tooth?Enamel crown, dentin, pulp cavity gingiva alveolar, root canal root cementum
Explain the mechanism of vomitting? Results from a complex reflex that empties the stomach another way. irration or distension in the stomach or intestines can trigger it.

The digestive system worksheet
(1)What is the digestive tract? A long, continuous tube with food first entering at the mouth
(2)What happens to undigested materials in the digestive tract? It exits out the anus along with dead cells, bacteria and other waste products
.3. Sketch the path that food takes through the digestive tract. Be sure to include the mouth, esophagus, stomach, duodenum, small intestine, appendix, large intestine rectum, and all 4 sphincters.
4. What is the function of the mouth in the digestion process? It brings the food into the body and breaks it down.
5. What is the term for the small mass of food that enters into the esophagus? Bolus
6. What triggers peristalsis? The presence of the bolus in the esophagus.
7. What is the function of the cardiac sphincter? It closes the entrance to the stomach and prevents its contents from re-entering the esophagus.
8. What is the mucous membrane? A protective layer that lines the entire digestive tract.
9. How long is the small intestine? Over 20 feet.
10. Where does most digestion and absorption of nutrients take place? In the small intestine.
11. What increase the surface area of the small intestine? Villi
12. What is the first section of the small intestine? What is its function? The duodenum. its receptors can detect the presences of hypo- and hyper-tonic solutions, acid and chemical changes in the chyme which, via the duodenum, affect the action of the entire gastrointestinal tract.
13. Where is bile stored? In the gallbladder
14. What is segmentation? A muscle contraction that breaks up the intestinal contents and mixes them with the digestive juices.
15. When does the ileocecal sphincter open? When the amount of food in the small intestine begins to build up.

21. What is the function of the following enzymes: amylase, lactase, maltase, sucrase, and lipase? Amylase- completes the process of hydrolyzing starch; Maltase
22. There are two ways that nutrients get into the blood stream. Describe each method. Some diffuse across the intestinal membranes and into the blood simply by flowing along the concetration gradient. Others must be forced through the membrane against a gradient, since their concentration in the blood is alreadt greater than it is in the intestinal lumen.
