Renal - Part 2

Question 1

27. Normally what protein is found in the Urine?

Answer 1

None

Question 2

28. The first protein to appear in the Urine in a Kidney disease is?

Answer 2

Albumin


Question 3

29. Net filtration pressure that aids filtration at the Renal Corpuscle?

Answer 3

18 mm of Hg


Question 4

30. Is filtration an active or a passive movement?

Answer 4

Passive process that does not require
any ATP


Question 5

31. What is the number of anastomosis in the Glomerulus?

Answer 5

Zero

Question 6

32. What percentage of the Filtrate will become Urine? 1000 ml of filtrate is formed,
how much will eventually becomes urine?

Answer 6

10 ml. Correct answer is that only 1% of the
filtrate becomes Urine.


Question 7

33. What happens to the 99% of the filtrate within the Nephron that does not become
Urine?

Answer 7

It is reabsorbed by the Nephron into the Interstitial space and taken up by the
capillaries that line alongside the Nephron (Peritubular network of capillaries)


Question 8

34. What hormone is primarily responsible for the reabsorption of Sodium? 


Answer 8

Aldosterone

Question 9

35. Where is Aldosterone produced and secreted from?

Answer 9

Zona Glomerulosa of the
Adrenal Cortex


Question 10

36. Who stimulates the Zona Glomerulosa?

Answer 10

Angiotensin 2


Question 11

37. How is Angiotensin 2 produced?

Answer 11

By the action of ACE (Angiotensin converting
enzyme) on Angiotensin 1

Question 12

38. How is Angiotensin 1 produced?

Answer 12

By the action of Renin on Angiotensinogen


Question 13

39. Who produes Angiotensinogen?

Answer 13

Liver

Question 14

40. What hormone is responsible for the reabsorption of water from the Nephron?

Answer 14

ADH
(antidiuretic hormone)


Question 15

41. Where is ADH produced? 


Answer 15

Hypothalamus

Question 16

42. Where is ADh secreted from?

Answer 16

Posterior Pituitary gland


Question 17

43. What is excess of ADH termed? 


Answer 17

SIADH

Question 18

44. In SIADH what will happen to the urinary output?

Answer 18

Less urinary output, more
concentrated urine. Urine Specific gravity will be high


Question 19

45. What is lack of ADH termed?

Answer 19

Diabetes Insipidus


Question 20

46. In Diabetes Insipidus what will happen to the urinary output?

Answer 20

More urinary output,
less concentrated urine. Urine Specific gravity will be low


Question 21

47. Can any substance be found in the Urine that is not filtered by the Nephron?

Answer 21

Yes by
the process of Secretion


Question 22

48. What are the three zones observed in the cut section of the Kidney


Answer 22

a. Cortex (outer zone)
b. Medulla (middle zone)
c. Pelvis (inner most zone)


Question 23

49. What are the three major processes that are involved in the creation of Urine by the
Nephron:


Answer 23

a. Filtration
b. Reabsorption
c. Secretion


Question 24

50. Counter current multiplier exchange mechanism happens at what location?

Answer 24

Loop
of Henle.

Question 25

26. Where do I find the Vasa Recta?

Answer 25

Following the long loop of Henle of the
Juxtamedullary nephrons
