  2. Structure

  3. Abdominal Quadrants

  4. Abdominal Regions

  5. Mouth • where the digestive process begins • consists of the tongue, salivary glands, teeth, and pharynx

  6. Esophagus • A tube 10 to 12 inches long that carries food from the mouth to the stomach

  7. Stomach • a hollow, muscular, J-shaped organ • holds food from 3 to 4 hours • has three parts: the fundus, body, and pylorus • produces gastric juices that help break down food

  8. Intestines • the small intestine: where most of the food the body needs are absorbed into the bloodstream • the large intestine: where most water is absorbed, wastes are changed into solid form

  9. Appendix • Part of the lymphatic system • attached to the cecum

  10. Liver • The largest gland in the body • helps control the amount of protein and sugar in the body by changing and storing excess amounts

  11. Gallbladder • a small hollow sac that is attached to the underside of the liver • it releases bile from the liver into the small intestine to help digest a fatty meal

  12. Pancreas • located behind the stomach • aids in the digestion of food • produces insulin

  13. Common Conditions of the Digestive System

  14. Malignancies • very common • symptoms depend on location • indigestion • vomiting • constipation • obstruction • bloody stool

  15. Ulcerations • a sore or tissue breakdown • common places: colon, stomach, duodenum • Gastric Ulcers caused by H Pylori bacteria

  16. Hernias • the intestine pushes through a weakened area of the abdominal wall

  17. Gallbladder Conditions • cholecystitis: inflammation of the gallbladder • cholelithiasis: formation of stones in the gallbladder

  18. Common Problems Related to the Lower Bowel • diarrhea: multiple watery stools • constipation: when stool passes through the colon too slowly – most severe form: fecal impaction • bowel incontinence: involuntary passage of fecal material from the anus

  19. Procedures Related to the Digestive System

  20. Nasogastric Tube

  21. NG Tube cont. • may be placed for stomach decompression (ex. – during CPR) • to give stomach rest • to relieve nausea

  22. Normal CT of Abd

  23. CT Scans • CTs may be done of abd/pelvis, with or without contrast (IV or PO) • used to diagnose abnormalities/conditions of digestive system
