Clarence had been cooking all day, getting Thanksgiving dinner ready for the whole family. After dinner, he bent over to pick up a serving dish and felt a sharp, stabbing pain in the right upper back just below his shoulder blade. The pain was so intense, he could hardly breathe. It lasted for about 20 minutes, then slowly dissipated to a dull ache. Having a history of back pain, he thought he had injured the same area again. The following Monday, Clarence’s doctor scheduled a magnetic resonance imaging (MRI) test to look at his spine. The test results showed nothing wrong with the skeletal system—no misalignment in the spine. There was also no change in the pain with movement. The dull ache in Clarence’s back remained constant, regardless of whether he was moving about or sitting still. A urinalysis came back normal. Over the next few days, the pain receded considerably. Then one night not long after, Clarence had fried chicken and gravy for dinner. About 10 minutes after eating, the stabbing pain returned. At this point, he remembered that he had eaten a lot of gravy at Thanksgiving too. Both types of gravy were very high in fat content. 10. Taking all the information into account, what system do you think may be malfunctioning to cause the pain? a. Skeletal system b. Muscular system c. Digestive system d. Urinary system

After eating foods high in fat, Clarence’s body may increase the production and release of bile. Bile is stored in which organ? a. Liver b. Pancreas c. Stomach d. Gallbladder 13. Identify the two main types of motility produced by the smooth muscle tissue in the wall of the gastrointestinal (GI) tract.

15. Name and describe three major types of cells in the gastric glands.

Answer key! 1. C 2. B 3. A 4. B 5. A 6. D 7. A 8. B 9. B 10. C 11. A 12. D 13. The two types of motility produced by the smooth muscle of the GI tract wall are peristalsis and segmentation. 14. Bile contains several substances that aid in digestion, specifically lecithin and bile salts. Bile also contains a small amount of sodium bicarbonate, which helps neutralize chyme. Excreted substances include cholesterol, products of detoxification, and bile pigments. 15. Parietal cells produce hydrochloric acid, endocrine cells secrete ghrelin and gastrin, and chief cells produce gastric enzymes. 16. detoxify various substances; secrete bile; carry on important steps in the metabolism of proteins, carbohydrates, and fats; store iron and vitamins A, B12, and D; produce plasma proteins; and serve as the site of hematopoiesis during fetal development. 17. Although very useful, one can survive without a gall bladder. It stores and concentrates bile from the liver; and without the gall bladder, the liver continues to secrete bile. Sometimes, removal of the gall bladder may require a patient to adjust their food intake (especially meals high in fat) to accommodate the change in the amount of bile available during digestion....
