What cause Na+ ions to move out at the bottom of the ascending limb. Also at the DCT that is found in the cortex, which isnt in the salty medulla, so what causes the water to move out of there, is that just because water potential of the capillary is lower than the filtrate??

Na/K/Cl pump in the ascending limb. And as for the water, it basically follows the ions, so as ions are pumped out of the filtrate, water will follow. The medulla's purpose is to allow you to regulate how much water you can reabsorb, but that's another story haha
