The small intestine has three parts: the duodenum, the jejunum, and the ileum.

小肠分为三个部分，分别为指肠、空肠与回肠。

He's suffering the pains of duodenal cancer.

他正遭受指肠癌痛苦。

But the duodenum is what you might call the business end of the small intestine.

但是指肠就是你所说小肠业端。

Then, it's sent to the first portion of the small intestine, which is called the duodenum.

然后它进入小肠第一部分，即指肠。

Inside the duodenal cells, iron molecules bind to a protein called ferritin, which temporarily stores the iron.

在指肠细胞内，含分子与一种称为蛋白蛋白质结合，蛋白会暂时贮存。

Normally, trypsinogen isn't activated until it is cleaved by protease enteropeptidase which is found in the duodenum.

通常情况下，胰蛋白酶原在被指肠中肠肽酶切割之后才会被激活。

The pancreas is a long, skinny gland the length of a dollar bill, snuggled around by the duodenum.

它是一个细长腺体，约等一美元纸币长度，位指肠周围。

Cholecystokinin stimulates acinar cells in the pancreas to secrete digestive enzymes that travel through the pancreatic ducts and into the duodenum.

胆囊收缩素也能刺激胰腺腺泡细胞产生消化酶；消化酶从胰腺导管排出，进入指肠。

A generous amount of bicarbonate is also secreted by a number of glands lying in the submucosa of the duodenal wall.

指肠肠壁上分布大量腺体，也可分泌大量碳酸氢盐。

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。

Those hormones in turn tell the gallbladder to contract and squirt bile through the cystic and bile ducts into the duodenum.

这些激素反过来告诉胆囊收缩并通过胆囊和胆管将胆汁喷射到指肠。

So you will cut, you know, one third, which will be the duodenum.

所以你会切掉大约三分之一，也就是指肠。

Yes. We're prepping him for an EGD.

没错 我们要给他作个食管胃指肠镜。

Following breakdown of food in the stomach, iron is released, and then it's absorbed in the small intestine - specifically, the duodenum.

随着食物在胃内分解，释放出来，接着被小肠吸收，确切说是在指肠。

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

（1）只有25厘米指肠，从胃中接收食糜，并协助调节胃排空。

As a result, the gallbladder wall can actually adhere to a nearby structure, most commonly at the duodenum, but occasionally to the stomach, colon, and jejunum.

胆囊壁会因而粘附周围脏器，最常见是指肠，有时也会粘附胃、结肠和空肠。

Early in 1917 he began suffering from a duodenal ulcer and he would eventually have to have this operated on early that winter.

1917年初，他开始患有指肠溃疡，最终那年冬天早期不得不接受手术。

Now, the duodenum communicates with the stomach in the last phase of gastric regulation that we talked about in the last episode — the intestinal phase.

现在，指肠在我们上集讨论过胃调节最后一个阶段和胃交流——肠道阶段。

The pancreas is along the lower curvature of the stomach, close to where it meets the first region of the small intestine, the duodenum.

5。胰腺在胃大弯附近，靠近胃与小肠始段（指肠）相接部位。

This is where the duodenum lets the stomach know, with hormones and nerve signals, when and how much chyme to release so it doesn't get overwhelmed all at once.

这是指肠通过荷尔蒙和神经信号让胃知道什么时候释放多少食糜，这样它就不会一下子被压垮。
