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消道，无法被动物消酶分解，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.

肠道微生物健康曾经是一种边缘医学关注点，现在已经成为人类主流，因为消道中细菌与肥胖、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，曾经食物告别了暂时支消道，到了光之下。

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

把们打开后，消道手风琴般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附属器官——除了消道之外东西，们永远不会与摄入物质接触，但在消过程中仍然起着至关重要作用。

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.

大肠——由结肠、直肠和肛门组成——相对较短，大约 1.5 米，为小肠提供了一个漂亮小框架，在消道末端。

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，我很确定你对这里关键选手很熟悉——们是形成连续管子中空器官，也就是你消道，也就是胃肠道，从你嘴延伸到你肛门。

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，消器官壁平滑肌轮流收缩和放松，以将食物挤出消道腔或腔。

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，辅助消器官——即肝脏、胰腺和胆囊——向消道分泌酶，在那里们伏击糊状物并将其分解成最基本学成分。

The hole in question is the alimentary canal.

所说洞是消道。

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，在消系统生态中充当关键物种，保持肠道细菌健康平衡。现在两年过去了，尽管privatella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流动，例如血管和消道，并且不受意识控制。
