Renal Endocrine

Question 1

Released by interstitial cells in the peritubular capillary bed in response to hypoxia

Answer 1

Erythropoietin

Question 2

Location of 1alpha-hydroxylase to make active Vitamin D

Answer 2

Proximal tubule

Question 3

Activate 1alpha-hydroxylase

Answer 3

PTH

Question 4

Secreted by JG cells in response to decreased renal arterial pressure and increased renal sympathetic discharge of beta-1

Answer 4

Renin

Question 5

Paracrine secretion that vasodilates the afferent arterioles to increased RBF

Answer 5

Prostaglandins

Question 6

Causes efferent arteriole constriction, increases GFR and FF and Na reabsorption in proximal and distal nephron

Answer 6

Angiotensin II

Question 7

Increases GFR and Na Filtration, Na loss and volume loss

Answer 7

ANP

Question 8

Secreted in response to increased plasma potassium and decreased blood volume, causes K and H secretion and Na reabsorption

Answer 8

Aldosterone

Question 9

secreted in response to increased plama osmolarity and decreased blood volume. Increases water channels to increase water reabsorption in principal cells

Answer 9

ADH (vasopressin)

Question 10

Causes increased calcium reabsorption in DCT

Answer 10

PTH

Question 11

Cause phosphate excretion in PT

Answer 11

PTH
