But if you were to somehow disconnect your heart from your autonomic nervous system, things, as you might imagine, would change.

但是如果以某种方式切断了心脏和自主神经连接，可以想象事情会发生改变。

This happens thanks to the parasympathetic division of the autonomic nervous system.

这要归功于自主神经副交感神经分支。

Normally, though, the heart rate is changed for short periods by the autonomic nervous system.

但是，正常情况下，自主神经会在短时间内改变心率。

When your brain's having to work harder, your autonomic nervous system drives your pupil to dilate.

Taking a look at a cross section chunk, there's also a layer of smooth muscle which has nerves of the autonomic nervous system in it.

来看一下这个横断面，这一层还有平滑肌，里面含有属于自主神经神经。

The sympathetic nervous system is part of the autonomic nervous system and it helps mediate your automatic functions like breathing, heart rate, sweating, and digestion.

交感神经是自主神经一部分，它有助于调节自动功能，如呼吸、心率、出汗和消化。

We remember that the autonomic nervous system is the division of the nervous system that's under involuntary control.

我们记得，自主神经是非自愿制神经分支。

The Autonomic nervous system. The Autonomic system deals with the visceral organs, like the heart, stomach, gland, and the intestines.

You may recall from our tour of the anatomy of your autonomic nervous system, that in both your sympathetic and parasympathetic divisions, almost every signal has to cross two synapses.

可能还记得我们对自主神经解剖介绍，在交感神经和副交感神经部门，几乎每个信号都必须通过两个突触。
