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

食道期，食物通过蠕动沿食道向下进入胃。

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

在微小幅度的肠蠕动下，食糜缓慢通过大肠；这个过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.

这里有许多机械动作和蠕动，但也有大量的化学消化。

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

这一叫做蠕动的过程也是食物通过胃和肠的方式。

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

周围食管组织中的神经感知推注的存在并触发蠕动，这是一系列明确的肌肉收缩。

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.

内环肌与外纵肌的活动共同形成了肠道的蠕动；肠蠕动就是指一系列协同进行的平滑肌的波状收缩，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.

食团在食管的蠕动下被送入胃内；胃内随即分泌胃酸，并在胃蛋白酶的作用下开始进行消化。

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，因为它会刺激实际的蠕动 - 即结肠肌肉的运动 - 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，肠管的波状收缩运动，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，消化器官壁的平滑肌轮流收缩和放松，以将食物挤出消化道的腔或腔。

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.

这些神经元通常会进行蠕动，这种肠道的挤压运动将食物推过肠道，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.

这个阶段叫做推进，它最初的机制是吞咽——如你所知，这是一个自愿的动作——但是很快就变成了非自愿的蠕动过程。

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的蠕动运动——巨大而强烈的收缩，同时清理一大片肠道，将粪便推入直肠。这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.

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