These then get snared in their alimentary canals, cannot be broken down by the animals' digestive enzymes and may ultimately kill them.

然后这些东西会陷入，无法被动物的酶分解，并最终可能致死。

Gut microbial health, once a fringe medical interest, is now mainstream for human beings, as bugs in the alimentary canal are linked with conditions ranging from obesity to arthritis.

微生物健康曾经是一种边缘医学关注点，现在已经成为人类的主流，因为中的细菌与肥胖、关节炎等一系列疾病有关。

And when that moment arrives, what was once food says farewell to the alimentary canal that temporarily held it, and passes back into the light of day.

当那一刻到来时，曾经的食物告别了暂时支撑它的，到了光天日之下。

And laid open, the accordion-like surface area of that alimentary canal would cover a small apartment.

把它们打开后，手风琴般的表面积将覆盖一个小公寓。

And this brings me to your crucial accessory organs — the things apart from the alimentary canal that never come in contact with ingested material, but still play an essential role in digestion.

这就把我带到了你至关重要的附属器官——除了之外的东西，它们永远不会与摄入的物质接触，但在过程中仍然起着至关重要的作用。

The large intestine — consisting of the colon, rectum, and anus — is relatively short, at about one and half meters, and it provides a nice little frame for the small intestine, here at the end of the alimentary canal.

——由结、直和肛门组成——相对较短，约 1.5 米，它为小提供了一个漂亮的小框架，在的末端。

Now, I'm quite sure that you're familiar with the key players here — they're the hollow organs that form the continuous tube that is your alimentary canal, aka the gastrointestinal tract, which runs from your mouth to your anus.

现在，我很确定你对这里的关键选手很熟悉——它们是形成连续管子的中空器官，也就是你的，也就是胃，从你的嘴延伸到你的肛门。

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，器官壁的平滑肌轮流收缩和放松，以将食物挤出的腔或腔。

And here, the accessory digestive organs — namely, the liver, pancreas and gallbladder — secrete enzymes into the alimentary canal, where they ambush the mush and break it down into its most basic chemical building blocks.

在这里，辅助器官——即肝脏、胰腺和胆囊——向分泌酶，在那里它们伏击糊状物并将其分解成最基本的学成分。

The hole in question is the alimentary canal.

所说的洞是。

I fidel bacterium is what is known as a probiotic organism something that acts as a keystone species in the alimentary ecosystem keeping the mixture of gut bacteria healthy Now two years later although levels of privatella have fallen back somewhat.

这种益生菌被认为是一种益生菌生物，它在系统生态中充当关键物种，保持细菌的健康平衡。现在两年过去了，尽管privatella的水平有所下降。

Smooth muscles are used to control the flow of substances within the lumens of hollow organs, for examples, blood vessels and the alimentary canal, and are not consciously controlled.

平滑肌用于控制空腔器官内物质的流动，例如血管和，并且不受意识控制。
