Toxic metabolites also affect the autonomic nervous system regulating gastrointestinal motility, and this can causes abdominal pain, constipation, and vomiting.

毒性代谢产物也可以影响调节胃肠蠕动的自主神经系统，可以导致腹痛、便秘和呕吐。

In fact, a 1999 study found that hot sauce significantly increased gastrointestinal motility, improving clearance and protection of the esophagus.

事实上，1999 年的一项研究发现， 辣酱可显着增加胃肠蠕动，改善食道的清除和保护。

Thus, the parasympathetic causes slower heart rates and respiratory rates, sleep, increased gastrointestinal track motility, increased peripheral vascular flow, blood flow to all cells, liver and kidneys, and venous return to the heart.

因此，副交感神经引起心率和呼吸频率减慢、睡眠、胃肠运动和周围血流增加、血液流向所有细胞、肝脏和肾脏以及静脉血回流到心脏。
