Chapter Thirteen – The Urinary System
1.
Describe all the organs of the urinary system.
2.
Explain how the nephron is the functional unit of the kidney.
3.
Describe the vascular and tubular components of the nephron.
4.
Outline the general characteristics of the following processes: glomerular filtration, tubular
reabsorption, and tubular secretion.
5.
Describe how several forces interact to produce glomerular filtration.
6.
Analyze the glomerular filtration rate and its regulation.
7.
Explain factors that influence glomerular filtration.
8.
Outline the mechanisms of tubular reabsorption, including the role of the sodium-potassium
ATPase pump.
9.
Analyze factors, drugs, and hormones that influence tubular reabsorption, including the
renin-angiotensin-aldosterone system.
10. Explain the concept of a tubular maximum for reabsorption.
11. Compare the substances that are regulated and not regulated by the kidneys.
12. Outline the mechanisms of tubular secretion, including the control of potassium and
hydrogen ions.
13. Analyze the processes of urine excretion and renal clearance.
14. Discuss the relationship between body hydration and urine excretion.
15. Outline the mechanism of countercurrent multiplication on nephron function.
16. Explain the varying vasopressin responses on water reabsorption to different conditions in
the solute/water concentration in the ECF.
17. Discuss the relationship between water/solute reabsorption to excretion.
18. Predict the consequences on body health from renal failure.
19. Explain the functions of the bladder and urethra during micturition.
20. Describe how kidney function contributes to homeostasis.
