Esophageal phase, in which the food passes down the esophagus, via peristalsis, into the stomach.

食道期，食物通蠕动沿食道向下入胃。

The chyme slowly moves through the large intestine through small waves of peristalsis that take place over hours or even days.

在微小幅度肠蠕动下，食糜缓慢通大肠；程长达数小时甚至数天。

Now there's a lot of mechanical action and peristalsis going on here, but there's also a ton of chemical digesting too.

里有许多机械动作和蠕动，但也有大量化学消化。

This process, called peristalsis, is also how food is moved through the stomach and intestines.

一叫做蠕动程也是食物通胃和肠方式。

Nerves in the surrounding esophageal tissue sense the bolus's presence and trigger peristalsis, a series of defined muscular contractions.

周食管组织中神经感知推注存在并触发蠕动，是一系列明确肌肉收缩。

Together, they perform what's called peristalsis, which is a series of coordinated wave-like muscle contractions that helps squeeze the food bolus in one direction.

内环肌与外纵肌活动共同形成了肠道蠕动；肠蠕动就是指一系列协同平滑肌波状收缩，可以挤压食团，确保食物向前移动。

The bolus is then moved by peristalsis through the esophagus and into the stomach, where hydrochloric acid is secreted and pepsin begins the digestion process.

食团在食管蠕动下被送入胃内；胃内随即分泌胃酸，并在胃蛋白酶作用下开始消化。

Start drinking it because it's going to stimulate the actual peristalsis - that's the movement of the muscles in the colon - to start moving again.

开始喝它，因为它会刺激实际蠕动 - 即结肠肌肉运动 - 再次开始运动。

What happens is that the normal wave-like contractions of the intestine, called peristalsis, grab this leading edge and pull it into the part of the bowel ahead of it.

通常情况下，肠管波状收缩运动，即肠蠕动，会把套叠前缘送入远端肠腔中。

In peristalsis, the smooth muscles of the walls of your digestive organs take turns contracting and relaxing to squeeze food through the lumen, or cavity, of your alimentary tract.

在蠕动中，消化器官壁平滑肌轮流收缩和放松，以将食物挤出消化道腔或腔。

These neurons would normally do the peristalsis, this kind of squeezing motion of the intestine that pushes the food through it and that allows us to absorb nutrients and water.

些神经元通常会蠕动，种肠道挤压运动将食物推肠道，使我们能够吸收营养和水分。

This stage is called propulsion, and its initial mechanism is swallowing — which, as you know, is a voluntary action — but then it's quickly turned over to the involuntary process of peristalsis.

阶段叫做推，它最初机制是吞咽——如你所知，是一自愿动作——但是很快就变成了非自愿蠕动程。

But most people also experience a few mass peristalsis movements a day — big, intense contractions that clear out a large swath of intestine at once, pushing feces into the rectum. These often occur just after eating.

但是大多数人一天也会经历一些大规模蠕动运动——巨大而强烈收缩，同时清理一大片肠道，将粪便推入直肠。些通常发生在刚吃完东西之后。

Okay, so without these nerves, peristalsis in the gut is seriously impaired, because those muscles tend to lose the ability to relax, and they stay in their default contracted position, which essentially blocks the movement of feces.

那一旦些神经缺失，肠道蠕动就会严重受损，因为些肌肉往往会失去舒张能力，停留在默认收缩形态，阻碍粪块移动。
