12
Q
How can glomerular filtration be controlled?
A
- Sympathetic nervous system increase increases GFR
- Constricting renal blood vessels - adrenaline, NA, endothelin - constricting efferent and efferent decreases GFR
- Constrict efferent arterioles - angiotensin 2 to increase GFR
- Decrease renal vascular resistance - nitrous oxide decreases vascular resistance and decreases GFR
- Vasodilation - caused by Prostaglandins and bradykinin. Increase GFR
13
Q
What is the macula densa?
A
A group of specialised epithelial cells that comes in close contact with arterioles.
The cells sense changes in volume delivery to the distal tubule.
Detects decrease in NaCl
14
Q
What happens when the volume of fluid being delivered to the kidneys is reduced?
A
Macula densa cells detect this by a drop in NaCl
This causes
Decreased resistance to blood flow in afferent arterioles
Increased renin release from juxta glomerular cells that leads to the construction of the efferent arterioles
15
Q
What effect do ACE inhibitors have on a reduced Renal arterial pressure?
A
They prevent the formation of angiotensin 2 and causes greater reductions of GFR when renal arterial pressure falls

38
What is the vicious cycle of end stage renal disease
Primary kidney disease causes a reduction in nephron number
