renal 5 Renal handling of sodium, potassium and water

?
sodium mainly reabsorbed (65%) by what? SODIUM
proximal tubule of nephron
1 of 17
sodium, this is for the most part reabsorbed (65%) from the proximal tubule of the nephron. This is a passive process (that is also coupled with bicarbonate reabsorption) and involves the activity of an enzyme, called? SODIUM
carbonic anhydrase
2 of 17
The next major site of sodium reabsorption (25%) is where SODIUM
the thick ascending limb of the loop of Henle
3 of 17
The next major site of sodium reabsorption (25%) is via? SODIUM
NaK2Cl cotransporter
4 of 17
5% of the filtered sodium load is actively reabsorbed from the? via? SODIUM
the distal tubule, via the NaCl cotransporter
5 of 17
Lastly, up to 5% of filtrate sodium can be reabsorbed from the SODIUM
late distal tubule / collecting duct
6 of 17
Lastly, up to 5% of filtrate sodium can be reabsorbed, regulated by what? SODIUM
aldosterone
7 of 17
Carbonic anhydrase inhibitors, loop diuretics (as NaK2Cl cotransport inhibitors), thiazide (and thiazide-like) diuretics (as NaCl cotransport inhibitors) and aldosterone antagonists (aka K-sparing diuretics) are what SODIUM
key agents that target sodium reabsorption around the renal tubule
8 of 17
65% reabsorbed from PCT passive or active? SODIUM
passive
9 of 17
25% reabsorbed from TAL of LH passive or active? SODIUM
active
10 of 17
5% reabsorbed from early DCT passive or active? SODIUM
active
11 of 17
5% reabsorbed from late DCT/CD passive or active SODIUM
passive
12 of 17
POtassium. 30% reabsorbed from TAL of LH but passive or actively?
actively
13 of 17
WATER. 10% reabsorbed from?
thin descending limb of LH
14 of 17
WATER Up to 25% reabsorbed from?
Collecting duct
15 of 17
water. absorption regulated by what?
ADH via insertion of water channels (aquaporins)
16 of 17
water. Up to 25% of filtered water is reabsorbed from the collecting duct – and this is known as facultative water reabsorption, under the influence of ADH acting on what receptors
