Flashcards in Reabsorption In The Kidney Deck (11):
1
How can you decribe reabsoprtion in the PCT?
Isosmotic, so that the ECF has the same osmotic pressure
2
How is sodium reabosrbed in the PCT?
Na+ is pumped across the basolateral membrane by 3Na+- 2K+ ATPase, Na+ moves across the luminal membrane down its conentration gradient using a membrane transporter or channel and water follows
3
What are the sodium transporters found in the PCT?
Na-H antiporter, and a Na-glucose symporter
4
What are the sodium transporters found in the loop of henle?
Na-K-2Cl symporter
5
What are the sodium transporters found in the early DT?
Na-Cl symporter
6
What are the sodium transporters found in the late DT and CD?
ENaC and RomK
7
What does SGLUT transport?
Two Na+ ions + 1 glucose agaisnt the concentration gradinet
8
What are some of the substances secreted in the tubule fluid?
Protons, potassium and organic anions and cations
9
How would you estimate the glomeluar filtration rate?
GFR= (concentration in urine x volume in urine)/plasma concentration
10
What is eGFR used for?
To estimate the creatinine clearnace
