9 Stomach Regions Cardiac Fundic Body (greater and lesser curvature) Pyloric
10 Stomach LiningGastric Juices contain acids that break down food - secreted by gastric glandsPEPSIN - most important digestive enzyme for breaking down foodMucus prevents stomach from digesting itself
11 Chyme - paste, after food has been broken down, released then into the duodenum via the pyloric sphincter valveRugae - folds within stomachGastric Pits contain glands to make juices
12 PANCREAS - secretes insulin which breaks down sugars Pancreatic Juice also breaks down fat
14 Liver - ducts and vessels Hepatic duct --> to common bile ductHepatic portal vein - circulates blood through liver
15 Liver Functions 1. blood glucose levels 2. breakdown of lipids and fats3. protein metabolism4. stores vitamins5. destroys damaged RBCs6. removes toxins7. secretes bile
16 Remember Bili Lights?Using bili lights is a therapeutic procedure performed on newborn or premature infants to reduce elevated levels of bilirubin. If blood levels of bilirubin become too high, the bilirubin begins to dissolve in the body tissues, producing the characteristic yellow eyes and skin of jaundice.
17 Gall Bladder - under liver cystic duct --> common bile duct stores bile, digests fat *gallstones may form
18 Membrane holds it together, contains blood vessels Small IntestineStarts at the pyloric sphincter1. Duodenum2. Jejunum3. Ileum*Mesentery Membrane holds it together, contains blood vessels
19 Greater Omentuma "curtain-like" membrane that covers the intestines, stores fat and lays like a drape
20 The main function of the small intestine is to secrete chemicals that break down food and carry the nutrients away in the blood stream. In one word:ABSORPTION
22 Function of Large Intestine Secretes mucus, reabsorbs water, contains bacteria to aid in digestion (intestinal flora)Mass Movements (defecation) - removes undigested foodThe main job is WATER REABSORPTION...
