3. Label and state the functions of the structures of the kidney.

6. Distinguish between the afferent and efferent arterioles.

8. Identify one component of the renal capsule which is an example of an extracellular component in animals.

10. Explain the process of ultrafiltration.

15. List three components of the blood which are not pushed into the glomerular filtrate and state the reason why.

17. Selective reabsorption returns valuable molecules to the blood.

18. State the location of selective reabsorption in the kidney.

20. List three molecules that are recovered back into the blood by selective reabsorption.

22. Explain the significance of the following elements of selective reabsorption.

23. Convolutions of the tubuleMicrovilliMitochondriaProtein pumps and channelsOsmosis

24. A major function of the kidney is to maintain the balance of water in the blood.

25. Define osmoregulation.

27. List three functions of water in animals.

31. State the location of osmoregulation in the kidney.

34. Distinguish between the descending and ascending parts of the loop of Henle.

39. Explain the role of the collecting duct in osmoregulation.

44. ADH is a hormone used in negative feedback control of blood water balance.

45. State the two parts of the brain involved in osmoregulation and their functions.

49. Calculate the concentration of urea in the urine.

50. Explain why such a large proportion of urea is removed from the blood.

51. Explain why no proteins and macromolecules are present in the filtrate or urine.

52. 100% of glucose is reclaimed. Explain how this occurs.

53. -428625201295Consider the urinalysis for patient B:

54. Calculate the percentage of glucose which is reuptaken to the blood.

55. Explain the presence of glucose in the urine of patients with diabetes. You will need to consider two processes in your answer: glucoregulation and osmoregulation.

63. Deduce, with a reason, the effective of taking an insulin shot on the urine glucose concentration of a patient with Type I diabetes.

66. Deduce, with a reason, the effective of taking an insulin shot on the urine glucose concentration of a patient with Type II diabetes.

69. The plasma solute concentration, plasma antidiuretic hormone (ADH) concentration and feelings of thirst were tested in a group of volunteers. These graphs show the relationship between intensity of thirst, plasma ADH concentration and plasma solute concentration.
