Activity 1
#1 After completing activity 1, compare and contrast the glomerular pressure and glomerular filtration rate for the following settings: afferent radius .50mm/efferent radius .30mm versus afferent radius .35mm/efferent radius .45mm. Explain the physiology behind the results you observed using the data gathered
Activity 2
#2. After completing activity 2, compare and contrast the glomerular pressure and glomerular filtration rate for the 80 mmHg and 90 mmHg beaker pressure trials (both with open valves). Explain the physiology behind the results you observed using the data gathered.
#3. After completing activity 2, choose one of the trials run that you think would most closely approximate the conditions seen with a large kidney stone blocking the ureter. Using data from this lab, explain what could lead to passing the kidney stone and what could lead to kidney damage if the stone will not pass easily. Give full and complete reasons for your answer.
Activity 3
#4. After completing activity 3 explain, physiologically, how changes in afferent and efferent arteriole diameter work to counteract a drop in blood pressure in regards to filtration rate and pressure. For full credit, support your answer with data from the activity and also explain the physiology behind the data.
#5. After completing activity 4 explain, physiologically, how changes in the concentration gradient of the fluid in the medulla cause changes in the urine volume. Explain the role of anti-diuretic hormone in this response and predict what would happen to urine volume if antidiuretic hormone was absent. For full credit, support your answer with data from the activity and also explain the physiology behind the data.
Activity 5
#6. Research what is meant by the phrase “tubular transport maximum”. Using the data from activity 5, explain the physiology of the tubular transport maximum for glucose and explain whether or not the tubular transport maximum was reached in this activity. Provide data to support your answer.
#7 After completing activity 6 explain, physiologically, how urine volume and potassium concentration are altered by the presence/absence of aldosterone and antidiuretic hormone both alone and together. For full credit, support your answer with data from the activity and also explain the physiology behind the data.
