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 Lab 14 The Urinary System BIO202L Simulated Urine Sample pH A 8 B 4 C 7 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/red C blue 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 purple D yellow Blue/green Table 7: Simulated Urine Yeast Test Lab 14 The Urinary System BIO202L Simulated Urine Sample A Bubbles Before Hydrogen Peroxide? Bubbles After Hydrogen Peroxide? no no B no no C no no D no no 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). Using the test results from each of the urine samples, diagnose the condition(s), if any, that each of the sample patients is experiencing. ” Table 9: Sample A Test Test Results pH 8 Glucose negative Protein negative Yeast negative Diagnosis normal Table 10: Sample B Test Test Results pH 4 Glucose positive Protein negative Yeast negative Lab 14 The Urinary System BIO202L Diagnosis Diabetes, renal glycosuria Table 11: Sample C Test Test Results pH 7 Glucose positive Protein positive Yeast negative Diagnosis diabetes Table 12: Sample D Test Test Results pH 6 Glucose negative Protein negative Yeast negative Diagnosis normal ”2. 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? ” ”3. 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? ” Experiment 3: Virtual Model – Urinary System Coloring Activity ”Insert image of Urinary System: Anterior View: ” Lab 14 The Urinary System BIO202L Experiment 4: Fetal Pig Dissection of the Urinary System ”Insert photo of your pig’s dissected kidney with your name clearly visible in the background: ” Lab 14 The Urinary System BIO202L [Show More]
