Medulla, Pelvis,renal artery, renal vein, ureter, nephron:ans:
4. functional unit of the
kidney:ans: nephron1 million
per kidney!

concentration(diluted)
17. Process taking place in nephron loop?:ans: Countercurrent
mechanism (dilutesthe urine). Can also create concentrated urine from
the Na+ absorbed in the ascending limb.
