This was apparently something that Beaumont observed first-hand, by dropping hunks of meat into a cup filled with St. Martin's personal gastric fluids.

这显然是博蒙特第一手观察到的，他把大块的肉扔进装满圣马丁个人胃液的杯子里。

Most signals that increase stomach activity get the job done by increasing the secretion of gastrin, which then stimulates the release of other gastric fluids, as well as stomach-muscle activity.

大多数增加胃活动的信号通过增加胃泌素的分泌来完成这项工作，胃泌素随后刺激其他胃液的释放，以及胃肌肉活动。
