Part A Reviewing Your understanding pg. A. Great of the gastrointestinal Tract name the class of the GI street that are described. 1. The layer the contracts to churn food or move food along. 2. Great consisting of a membrane that lines a human body cavity that opens up to the overlays smooth muscle. 3. Areolar connective organization layer located deep to the mucosa. 4. A serous membrane the is the external layer the a GI street organ. B. Gastrointestinal tract Organs write the name of the term the is described. 1. That is only role is propulsion. 2. A continuous digestive pipe from the mouth to the anus. Canal 3. Conducts both air and food. 4. Major site that nutrient is created of 3 sections. Intestine 5. Section of little intestine that receives bile, pancreatic secretions, and food from the stomach. 6. Churns food and also begins protein digestion. 7. Has two sphincters that regulate elimination that feces native the body. 8. Has regions called the cardia, fundus, body, and also pylorus. 9. Has regions dubbed the cecum, colon, rectum, and also anal canal. Intestine 10. Receives secretions from salivary mastication wake up here. C. Gastrointestinal tract Organs and also Associated structures Write the surname of the organ that is described. 1. Extensions increasing surface ar area in the tiny intestine. 2. Folds in the gastric mucosa. 3. Permanent deep ridges in the tiny intestine mucosa. Folds 4. Sphincter valve between the stomach and duodenum. Sphincter 5. Serous membrane the lines the abdominal wall. Peritoneum 6. Serous membrane the covers the abdominal muscle organs. Peritoneum 7. Sphincter the connects the tiny and large intestine. Sphincter 8. Liquid that starts digestion the carbohydrates. 9. Bony plate in between the mouth and also nose. Palate 10. Develops a brush expansion of epithelial cabinet plasma membrane. 11. Keeps food and also fluids from going up right into the nasopharynx. 12. Area between the lips and teeth. 13. An ar of the stomach whereby the lower esophageal sphincter meets the stomach. 14. Has actually regions called ascending, transverse, descending, and sigmoid. Intestine 15. Narrowed an ar of the stomach before the small intestine. 16. A series of gathered pouches in the huge intestine. D. Accessory digestive Organs and also the Peritoneum create the name of the body organ that is described. 1. Mechanically breaks up food during mastication. 2. Secretes enzymes the digest carbohydrates, proteins, lipids, and nucleic acids. 3. Salivary glands located under the tongue v ducts that open up in the floor that mouth. Sublingual 4. Produces and secretes bile right into ducts. 5. Peritoneal membrane the holds the small intestine to the posterior ab wall. Mesentery 6. The secretions the this gland sign up with with bile to enter the duodenum. 7. Peritoneal fold that holds the liver come the anterior abdominal wall. Ligament 8. Manipulates food in mastication. 9. Fatty, huge fold of peritoneum spanning the transverse colon and small intestine. Higher Omentum 10. Biggest salivary glands whose ducts open up the upper second molars. Glands 11. Stores and secretes bile right into the duodenum. 12. Peritoneal membrane the attaches the stomach and duodenum to the liver. Omentum 13. Salient glands who ducts open lateral come the lingual frenulum. 14. Map bile native its cheap to the gallbladder for storage and concentration, and also then to the duodenum, listing the frameworks using (a) hepatocytes canaliculi ducts and right hepatic ducts hepatic duct duct (g) gallbladder duct hepatic duct duct (k) duodenum 15. Map blood native the hepatic portal vein through the liver to the worse vena cava, listing the frameworks using 6. Ileum GI tract 7. Diaphragm 8. Stomach GI tract 9. Transverse Colon GI street 10. Diminish Colon GI street 11. Jejunum GI tract using Your understanding pg. A. Digestive mechanism Structure 1. A hiatal hernia or failure of the lower esophageal (cardiac) sphincter to close reasons the stomach contents to ago up right into the esophagus. This reasons the esophageal wall surface to have actually a burning sensation (heartburn) and, in severe cases, bleeding. What reasons the burn sensation and also bleeding come occur? The burn sensation is resulted in HCl reflux indigenous the stomach. The caustic acid eats away and also destroys the mucosal lining and the blood vessels, causing bleeding 2. Just how does remove of the gallbladder affect digestion? remove of the gallbladder go not affect digestion. Once fats space ingested, the liver is engendered to create bile and secretes it through hepatic ducts, to the common hepatic duct, come the usual bile duct. It could possibly reason some problems with fat digestion due to the fact that the release of bile will not be together controlled. B. Identification of Digestive system Structures determine the structures numbered top top the the the human being stomach shown in 3. Rugae 4. Duodenum 5. Pyloric Sphincter 6. Pyloric Antrum recognize the frameworks numbered on the that the reduced GI tract, displayed in 7. Transverse Colon 8. Haustra 9.
