Function A. Reviewing Your Knowledge pg. 593-596

A. Layers of the Alimentary canal

Name the layers of the GI tract that are described.

1. The layer that contracts to churn food or motion nutrient along
2. Layer consisting of a membrane that lines a body crenel that opens to the exterior; overlays smooth muscle
3. Areolar connective tissue layer located deep to the mucosa.
4. A serous membrane that is the external layer of a GI tract organ.

B. Gastrointestinal Tract Organs

Write the proper name of the term that is described.

1. Its just office is propulsion.
2. A continuous digestive tube from the mouth to the anus.
3. Conducts both air and food.
4. Primary site of nutrient absorption; is equanimous of 3 sections.
5. Section of small intestine that receives bile, pancreatic secretions, and nutrient from the stomach.
6. Churns nutrient and begins protein digestion.
7. Has ii sphincters that control elimination of feces from the body.
8. Has regions called the cardia, fundus, body, and pylorus.
9. Has regions called the cecum, colon, rectum, and anal culvert.
10. Receives secretions from salivary glands; mastication occurs here.

C.Gastrointestinal tract Organs and Associated Structures

Write the name of the organ that is described.

1. Finger-like extensions increasing expanse in the small intestine.
2. Folds in the gastric mucosa.
3. Permanent deep ridges in the small intestine mucosa.
4. Sphincter valve between the stomach and duodenum.
5. Serous membrane that lines the intestinal wall.
6. Serous membrane that covers the abdominal organs.
7. Sphincter that connects the small and large intestine.
8. Fluid that begins digestion of carbohydrates.
9. Bony plate between the mouth and nose.
10. Forms a brush edge; extension of epithelial prison cell plasma membrane.
11. Keeps food and fluids from going up into the nasopharynx.
12. Area between the lips and teeth.
13. Region of the stomach where the lower esophageal sphincter meets the stomach.
14. Has regions called ascending, transverse, descending, and sigmoid.
15. Narrowed region of the breadbasket before the minor intestine.
16. A series of gathered pouches in the large intestine.

D. Accompaniment Digestive Organs and the Peritoneum

Write the name of the organ that is described.

1. Mechanically breaks upwards food during mastication.
2. Secretes enzymes that assimilate carbohydrates, proteins, lipids, and nucleic acids.
3. Salivary glands located under the tongue with ducts that open in the flooring of mouth.
4. Produces and secretes bile into ducts.
5. Peritoneal membrane that holds the pocket-size intestine to the posterior abdominal wall.
6. The secretions of this gland join with bile to enter the duodenum.
7. Peritoneal fold that holds the liver to the anterior abdominal wall.
8. Manipulates food in mastication.
9. Fat, large fold of peritoneum covering the transverse colon and small-scale intestine.
10. Largest salivary glands whose ducts open by the upper second molars.
11. Stores and secretes bile into the duodenum.
12. Peritoneal membrane that attaches the stomach and duodenum to the liver.
13. Salivary glands whose ducts open lateral to the lingual frenulum.
14. Trace bile from its secretion to the gallbladder for storage and concentration, and and so to the duodenum, list the structures in order, using Figure 10.
15. Trace blood from the hepatic portal vein through the liver to the junior vena cava, listing the structures in gild, using Effigy 12

East. Identification of Digestive Organisation Organs

Identify the organs in Figure 34.13 and state whether the organ is a GI tract organ or an accessory digestive organ.

Part B. Using Your Knowledge pg. 597-598

A. Digestive System Construction

1. A hiatal hernia or failure of the lower esophageal (cardiac) sphincter to shut causes the stomach contents to back up into the esophagus. This causes the esophageal wall to have a burning sensation (heartburn) and, in serious cases, haemorrhage. What causes the burning sensation and bleeding to occur?
2. How does removal of the gallbladder bear upon digestion?

B.  Identification of Digestive Organization Structures

Identify the structures numbered 3–6 on the X-ray of the human stomach shown in Figure 34.14.

Place the structures numbered 7–10 on the X-ray of the lower GI tract, shown in Figure 34.fifteen.
