XPFMember said:ermm i don't know if it's because i lack knowledge abt the topic
see..when the composition of the glomerular filtrate is always same as that of blood plasma except that it has no proteins.. then how come in this case we see that conc. of urine increases...and why in the collecting duct the water is more??
EXACTLY!!!!!!!!!!!!!!!!!XPFMember said:Jazak Allah Khairen!
so..is this correct: As the filtrate passes through the PCT , substances like glucose and amino acids are completely reabsorbed. Some of the water is also reabsorbed. Most of the urea stays in. Therefore, the concentration of urea in the urine becomes higher than that in the filtrate as seen by the values in the table!

Please, help me with this question:
Describe the function of vasa recta.
Mark scheme points:
-removing water;
-from/ reabsorbed by collecting ducts;
-ref. to maintain water potential gradient (in medulla)
Jazakumullah Khair..
