Primary Examination SAQs 
Hi Amanada,
Great site, I visit it almost everyday!
Small possible correction with 2005A(11) – I think V1 receptors cause vaso-constriction and V2 cause aquaporin insertion, not the other way around as listed.

Thanks Stuart – glad to hear it is a useful site. Sorry for the delayed response – I am busy studying for the Part 2…but relevant corrections have been made! Good luck with the exam!
– A.

Hi Amanda,
Thank you for maintaining this wonderful website.
Possible correction with 2006A11 (reading from Ganong)
Angiotensin 2 – renal effect – constricts efferent > afferent – this should increase GFR (chaper 38), but also angiotensin 2 causes mesangial cells to contract decreasing surface area for filtration (decreasing Kf) so decreasing GFR overall (chapter 24).

Thanks for the feedback Dennis – it certainly seems your understanding of renal physiology is sound! If you are able to convey that in the exam, it would definitely be high scoring! Otherwise, the overall effect (which we agree is n overall decrease in GFR) would probably suffice

Hi Amanda. Great site; I am visiting it more and more as time passes. Just a comment about 2011a(11)/2003a(16) (Loop of Henle). You have written that the cortical nephrons (short loop) have a thin ascending limb and that the juxtamedullary nephrons (long loop) have a thick ascending limb. From what I have read so far, it seems the cortical nephrons have only a thick ascending limb, whereas the juxtamedullary nephrons have both a thin ascending and a thick ascending limb. Therefore the sodium and chloride reabsorption in the cortical nephrons is by active mechanism (thick limb) and the sodium and chloride reabsorption in the juxtamedullary nephrons is by passive (in the thin limb) and active (in the thick limb) processes. That is from page 88-89 Vander’s Renal Phys 7th ed. Regards 🙂
