Endocrine Functions Flashcards
1
Q
Renin
A
Secreted by the juxtaglomerular apparatus in the kidneys
Converts angiotensinogen to angiotensin I
Angiotensin I converts to angiotensin II
2
Q
Angiotensin II
A
Controls renal bloodflow
1) Constricts renal arterioles
2) Secretion of aldosterone helps retain sodium
3
Q
Aldosterone
A
Promotes reabsorption of Sodium (with water) from filtrate, and secretion of Potassium from blood into filtrate
4
Q
Antidiuretic hormone
A
Promotes water reabsorption from filtrate, in the distal convoluted tubule and collecting duct
5
Q
Parathyroid hormone
A
Promotes Calcium reabsorption and excretion of phosphate from filtrate
