| Question | Answer |
|---|---|
| What anchors the liver to the abdominal wall? | Falciform ligament |
| What is the greater omentum? | Fatty apron used for cushion and protection; also seals off infections and causes adhesions |
| What anchors the small intestine to the posterior wall? | Mesentery |
| Where is the lesser omentum found? | Liver to the lesser curvature of the stomach |
| What is the pathway for the greater omentum? | Greater curvature then goes down then back up and attaches to the transverse colon |
| What muscle is found near the pharynx and esophagus? | Inferior pharyngeal constrictor |
| What provides sympathetic innervation to the esohpagus? | Sympathetic trunk |
| What type of muscles make up the esophagus? | Skeletal and smooth |
| What vertebral level is the esophageal hiatus found? | T10 |
| Where are hiatal hernias and GERD found? | Where the diaphragm and internal esophageal sphincter empty into stomach |
| What is the blood supply to the esophagus? | Esophageal branches from thoracic aorta |
| What increases nutrient absorption? | Smaller pieces of food, rugae (increases surface area) |
| What is the major function of the stomach? | Mix and breakdown ingested food |
| What is chyme? | Mix of ingested foodand gastric juices |
| Where is the lesser curvature found? | Between liver and stomach |
| What is the blood supply to the lesser curvature? | Left and right gastric arteries and veins |
| Where is the greater curvature found? | Between stomach and transverse colon |
| What is the blood supply to the greater curvature? | Left and right gastro-omental arteries and veins |
| What does the pyloric sphincter do? | Helps further break down food by not allowing large pieces to move on to the duodenum |
| What are the three main branches of the aorta that supply this area? | Celiac trunk, superior mesenteric artery, inferior mesenteric artery |
| What are the three branches from the celiac trunk? | Left gastric, splenic, and common hepatic arteries |
| What are the two branches of the common hepatic artery? | Gastroduodenal and proper hepatic |
| What are the two branches of the proper hepatic? | Right and left hepatic arteries |
| What usually branches off the right hepatic artery? | Cystic artery |
| What does the superior mesenteric branch into? | Ileocolic, right colic, and midde colic arteries |
| What does the inferior mesenteric artery branch into? | Left colic, sigmoid, and superior rectal arteries |
| What is the major site for absorption of nutrients? | Duodenum |
| What is the blood supply to the duodenum? | Gastroduodenal and pancreatic arteries |
| Where do nutrients continued to be absorped? | Jejunum |
| What is the blood supply to the jejunum? | Superior mesenteric artery |
| Where is nurtient pretty much done at? | Ileum |
| What is the blood supply to the ileum? | Superior mesenteric artery |
| As you go from proximal jejunum to terminal ileum, what changes? | Less folds in the lumen so less absorption |
| What are the three distinguishing features of the large intestine? | Haustra, tineae coli, omental appendages |
| What is the large intestine's job? | Reabsorp water and compact waste |
| What are the six parts of the large intestine? | Cecum, ascending, transverse, descending, and sigmoid colons, and rectum |
| What arteries supply the large intestine? | Superior and inferior mesenteric arteries |
| What does parasympathetic innervation to the large intestine? | Vagus (to left colic flexure) and pelvic splanchnics (S2-S4, after left colic flexure) |
| What are the fat tabs on the large intestine called? | Omental appendages |
| What kind of blood does the portal vein carry? | Oxygen poor, nutrient rich, can be toxic |
