The table shows the percentages of some substances measured in fluid taken from a human kidney.
Which letter on the diagram shows the most likely source of the fluid?
A A
B B
C C
D D
E E
Hi the answer is B. Can someone explain this question in detail?
I think the Water is the biggest indicator here, B is before the descending limb where we would see the levels of Water go down as they leave the nephron, A would probably have a smaller water %, as would C probably, E would have more Urea % as well by that point, D would have proteins in it as they wouldnt be able to leave the glomerulus due to their size.
