Bicarbonate helps neutralize the acidic chyme, and raising the pH in the intestinal lumen also helps digestive enzymes work more effectively.

碳酸氢盐能够中和酸性的食糜，还能提高肠腔内的pH值；这也可以提高消化酶的活性。

The large intestine absorbs excess water from the chyme, and that helps condense it into dry fecal matter.

大肠可吸收食糜中多余的水份，如此可将食糜浓缩成干燥的粪便。

It gets the signal when chyme slides into the duodenum, which activates the enteroendocrine cells to release a pair of hormones.

当食糜滑入十二指肠时，它会得到信号，这会激活肠内分泌细胞释放一对激素。

These substances help transform food present in the stomach into a semifluid substance called chyme.

这些物质有助于将胃中存在的食物转化为一种叫做食糜的半流体物质。

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。

The pyloric sphincter allows food to pass into the small intestine only after it has been transformed into chyme.

幽门括约肌使食物在转化为食糜后才能进入小肠。

(1) The duodenmn, which is only a 25cm section, receives chyme from the stomach, helps regulate gastric emptying.

（1）只有25厘米的十二指肠，从胃中接收食糜，并协助调节胃排空。

Now, once the stomach is done, doing what stomachs do, the pyloric sphincter opens, allowing the chyme to pass into the small intestine.

当胃部的工作完成后，幽门括约肌便会打开，使食糜顺利进入小肠。

When chyme hits the cecum, it's met by trillions of bacteria that colonize the large intestine - they're collectively called the gut microbiome.

一旦食糜进入盲肠，便立即与数以万亿计的细菌接触；这些细菌定植于大肠，它们统称为肠道微生物群落。

And while homebrewed intestinal juices help digest the chyme that your stomach turns food into, the real power actually comes from the outside helpers — the liver, gallbladder, and pancreas.

虽然自制肠液有助于消化胃将食物转化为的食糜，但真正的力量实际上来自外部助手——肝脏、胆囊和胰腺。
