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

食道期，食物通过蠕沿食道向下进入胃。

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

在微小幅蠕下，食糜缓慢通过大；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.

这里有许多机械作和蠕，但也有大量化学消化。

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

这一叫做蠕过程也食物通过胃和方式。

Rather, like the small intestines, each ureter features a layer of smooth muscle that contracts to move urine using peristalsis.

相反，像小一，每个输尿管都有一层平滑肌，该平滑肌通过蠕收缩以移尿液。

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

周围食管组织中神经感知推注存在并触发蠕，这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.

内环肌与外纵肌活共同形成了道蠕；蠕指一系列协同进行平滑肌波状收缩，可以挤压食团，确保食物向前移。

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，因为它会刺激实际蠕 - 即结肌肉运 - 再次开始运。

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，管波状收缩运，即蠕，会把套叠前缘送入远端腔中。

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.

这些神经元通常会进行蠕，这种道挤压运将食物推过道，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，它最初机制吞咽——如你所知，这一个自愿作——但很快变成了非自愿蠕过程。

And finally, the innermost layer is the renal pelvis, a funnel-shaped tube surrounded by smooth muscle that uses peristalsis to move urine out of the kidney, into the ureter, and into the bladder.

最后，最内层肾盂，一个被平滑肌包围漏斗状管，利用蠕将尿液从肾脏移出，进入输尿管，进入膀胱。

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.

但大多数人一天也会经历一些大规模蠕运——巨大而强烈收缩，同时清理一大片道，将粪便推入直。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，道蠕会严重受损，因为这些肌肉往往会失去舒张能力，停留在默认收缩形态，阻碍粪块移。
