Answer 1

erythropoietin (EPO)

Question 2

What makes aldosterone?

Answer 2

adrenal cortex

Question 3

What is the basic role of aldosterone on the kidney?

Answer 3

causes sodium reabsorption and potassium secretion resulting in increased serum sodium, increased blood volume, and increased blood pressure

Question 4

What makes ADH?

Answer 4

posterior pituitary

Question 5

What is the basic role of ADH in the kidney?

Answer 5

causes water reabsorption by causing epithelial cells of the distal nephron to become permeable to water

Question 6

When is ADH secreted?

Answer 6

plasma volume is too low
blood pressure is too low
plasma osmolarity is too high

Question 7

What makes calcitonin?

Answer 7

C cells

Question 8

When is calcitonin secreted?

Answer 8

when serum calcium is too high

Question 9

What is the basic role of calcitonin in the kidney?

Answer 9

causes calcium to be removed from the blood by deposition in bone, reduced reabsorption in the gut, and excretion in urine

Question 10

What makes parathyroid hormone?

Answer 10

parathyroid gland

Question 11

What is the basic role of parathyroid hormone in kidney?

Answer 11

opposite of calcitonin; causes addition of calcium into blood

Question 12

What is the basic role of erythropoietin in the kidney?
