Lecture 7 Flashcards
Renal veins dump into:
IVC
Renal arteries come off:
Descending aorta
Cells that contain receptors specific for a hormone are called:
Target cells
What converts Angiotensin I into Angiotensin II?
Angiotensin converting enzyme
What converts the enzyme Angiotensinogen into Angiotensin I?
Renin
Angiotensin II causes:
Adrenal gland to secrete Aldosterone
What does Aldosterone do?
Increases collecting duct permeability
Decrease in extracellular pressure near _______ causes _________ to release the hormone _______
- Distal convoluted tubule
- Juxtaglomerular cells
- Renin
With increased duct permeability: (4)
- Urine volumed decreased
- Fluid retained
- Blood volume increases
- Blood pressure back up
