Does anyone know the answer of the one with the arrow pointing downwards only?

I really thought that as well...but my friends were saying it was wrong! But it makes senseeeeeeeeeee!!! They were saying xylem..but its not like water goes DOWN the xylem?!
Anyway, i think stomata was right...

can anyone xplain hw kidney transport glucose by VEIN?

Ok well, the blood that enters the kidney goes through the artery, which then passes into those tiny nephrons. In the nephron the blood has high concentrations of urea, water, glucose, oxygen. This passes into the glomeroulous and under high pressure passes through to the  bowmans capsule. It then passes through to the first coiled tubule where ultra filtration takes place of some glucose and oxygen. It then passes down to the loop of henle where water is absorbed. Then it passes into the second coiled tubule where the final absorbtion of glucose takes place. This glucose absorbed in the first and second coiled tubule then pass into the blood stream through the renal vein. And finally, urea passes into the collecting duct and through to the ureter.

I hope that helped. It seams pretty complicated ;p
