✔ 最佳答案

cone-like structure = Loop of Henle( U shape)
The ascending limb of Loop of Henle is permeable to ions, so ions can move in from medullas to Loop of Hendle, this reduces the water potential of the filtrate, so less water lost from our body.
The descending limb of Loop of Hendle is permeable to water, so water can move out from Loop of Hendle to medulla, this reduces the water potential of the filtrate, so less water lost again.
Hope it is helpful.

Since it has a U shape, ascending limb is the part going up, descending limb is the part going down
