Lab #7 - Urinary System BIO169 lab online Experiment 1: Kidney Filtration Table 1: Solutions Present in Each Container before 60 Minute Submersion Solution ... Dialysis Tubing Beaker Table 2: Solutions Present in Each Container after 60 Minute Submersion Solution Dialysis Tubing Beaker Post-Lab Questions 1. What specific part of the kidney does the dialysis tubing represent? What is this part’s function? 2. What does the yellow food coloring represent at the end of the experiment? What does the Congo red represent? 3. Why is it important that the kidney filters the blood? Experiment 2: Urinalysis Table 4: Simulated Urine pH Test Simulated Urine Sample pH A 7 B 5 C 8 D 6 Table 5: Simulated Urine Glucose Test Simulated Urine Sample Color before Hot Water Bath Color after Hot Water Bath A Blue Blue B Blue Dark Orange C Blue Light Orange D Blue Blue Table 6: Simulated Urine Protein Test Simulated Urine Sample Color before Biuret Solution Color after Biuret Solution A Clear Blue B Clear Green C Clear Blue/ Purple D yellow/green Blue/ Green Table 7: Simulated Urine Yeast Test Simulated Urine Sample Bubbles Before Hydrogen Peroxide? Bubbles after Hydrogen Peroxide? A No No B No No C No No D No No Table 8: Simulated Urine Ketone Test Simulated Urine Sample Odor Observation A None B None C None D None Post-Lab Questions 1. Fill in Tables 9 through 12. Refer to Table 3 to determine if each result was normal or abnormal. If abnormal, include the data which indicates this (e.g., a pH of 3.2 means that glucose is present). Table 9: Sample A Test Test Results PH Normal Glucose Normal Protein Normal Yeast Normal Ketones Normal Table 10: Sample B Test Test Results PH Normal Glucose was present Protein Yeast Ketones Normal Table 11: Sample C Test Test Results PH Glucose was present Protein protein in it Yeast Normal Ketones Normal Table 12: Sample D Test Test Results PH Glucose Protein Yeast N Ketones N 2. Using the test results from each of the urine samples, along with the Table 3, diagnosis the condition(s), if any, that each of the sample patients is experiencing? 3. If you were a doctor and a patient’s urinalysis came back with high level of glucose, ketones and an acidic pH, what diagnosis would you immediately look into? 4. If you were a doctor and a patient’s urinalysis came back with an alkaline pH and high levels of protein, what diagnosis would you immediately look into? 5. What other conditions can urine be used to test for? Experiment 3: Virtual Model - Urinary System Coloring Activity Experiment 4: Fetal Pig Dissection of the Urinary System Post-Lab Questions 1. Label the arrows in Figure 11. A. Renal medulla B. major calyx C. Cortex D. Renal artery E. Renal vein F. Ureter 2. What is the function of the urinary bladder? 3. Would you think the kidneys are highly vascularized? 4. What is the function of the adrenal glands? 5. Explain, in detail, the process by which urine is made? The process of urine formation is disrupted or inhibited, over an extended period of time, toxins begin to accumulate in the body and this can cause quite serious medical conditions and eventually results in death.
