Type A is completely erratic and is independent of the plasma osmolality.

A型为ADH释放紊乱，且独立于血浆渗透压变化。

When I drink a glass of water and that water is absorbed into my blood, my plasma osmolality drops, which means I'm diluting my blood with the water.

当我们饮用一杯水后，水分吸收至血液中，血浆渗透压降低，意味着血液被稀释。

The part of my brain called the hypothalamus sees this drop in plasma osmolality and tells the pituitary gland to slow down the release of ADH (that's enough! ) .

当下丘脑感知到血浆渗透压的下降，就会让垂体减缓ADH的释放：“够了够了！”

Now suppose ADH continues to be released even though my plasma osmolality has dropped, we're going to continue retaining water, and as we drink more and more water, we might expect our plasma osmolality to continue dropping.

现在假设即便血浆渗透压已经下降，ADH仍在继续被释放入血，水分就一直保留在血管内，再加上我们继续饮水，可以预想到血浆渗透压继续降低。
