Inside the layers of detrusor muscles are millions of stretch receptors that get triggered as the bladder fills.

在逼尿肌里有千万层交织成网的牵张感受器，当膀胱尿量增加时会牵拉这些感受器。

For the next few hours, as my stomach grows distended from the food, it activates stretch receptors that again stimulate my medulla and get my vagus nerves to tell my stomach to turn up the juice.

在接下来的几个小时里，当我的胃因食物而膨胀时，它激活了伸展感受器，再次刺激我的髓质，让我的迷走神经告诉我的胃把胃酸调高。
