4. Joe was getting his patellar reflex tested. At first he was paying attention to the reflex Then he started thinking really hard about his SCB204 exam and his reflex response became stronger. Explain why this stronger response occurred. (3.5 pes) Digestive System structure and function (12.5 pts) S. A. Name the organ shown to the left: (1 pt) B. Name the structure labeled A (in the circle) (pt) C. What type of cells do you find in this organ? What does this cell seertete? (1 pt) 6. A. Name the organ shown to the left: (pt) B. Name ons structure seen in the image to the left that is not found in other digestive organs (pt) C. Describe how this structure contributes to the function of this organ. (2 pes)
7. Describe one function that rugae and circular folds have in common. (1.5 pts) 8. A. Name one difference between the mucosa of the mouth and the mucosa of the small intestine (1.5 pts) B. How does this difference contribute to the different functions of the mouth and small intestine? (2.5 pts) Digestive Physiology (12.5 pts) Group A ran an experiment to test for the break down of fatty acids. They puf vegetable oil with lipase into a tube at 37°C for 30 minutes. When they ran an assay to test for the presence of fatty acids, they got a negative result. 9. Give an explanation for this result. (2 pts.)
Group B used pepsin to break down BAPNA. BAPNA is also the assay to test for the presence of amino acids The results are shown below. All tubes were incubated at 37°C. Tube number 1 Contents of tube BAPNA 2 Pepsin 3 BAPNA pepsin 4 BAPNA + pepsin in pH9 5 BAPNA pepsin boiled for 4 min Result of assay 10. Why is the result negative for tube #2? (2 pts) 11A. Based on Group B's results above, what is the effect of high pH on the ability of pepsin to break down BAPNA? What data from above supports your answer? (2 pts.) B. Recall our experiment in lab. What effect did high pH have on the ability of trypsin to break down BAPNA? (2 pts) C. Did high pH have the same effect on the ability of pepsin and trypsin to break down BAPNA (compare your answer in 11A and 11B? Yes or no (circle one) Based on your answer, suggest a reason why high pH would have the have the same or different effect on trypsin and pepsin. (2 pts) 12. Give an explanation for the negative result in tube 55. (2 pts)
Urinary System (12.5 pts) 13. Briefly describe the location of the human kidneys. (1.5 pts) 14. In urine formation, where does filtration occur? (1 p.) 15. A person's blood is too acidic. Describe how tubular secretion would help restore pH balance of the blood. (3 pts.) 16. A. List the order of the blood vessels leading to the glomerular capillaries. Begin with the renal artery. (4 pts) B. Name one difference in the pathway of blood flow returning from the glomerulus to the renal vein. (1.5 p) 17. A patient has albumin in his urine, Suggest a reason for this abnormality. (1.5 pts)
