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

小肠三个部，别十二指肠、空肠肠。

The final portion is called the terminal ileum, and it absorbs vitamin B12 and bile salts which are recycled.

最后一部末端肠，可以吸收维生素B12和胆汁盐（进行胆盐循环）。

(3) The last section, the ileum is attached to the large intestine.

（3）最后一部的肠大肠相连。

There are a ton of tiny lymph nodes sprinkled throughout the intestines called Peyer's patches, and they're particularly common in the ileum.

肠腔中散布着大量微小淋巴，称Peyer集合淋巴，以肠最多见。

Unlike the jejunum, the ileum is also capable of undergoing structural and functional adaptations to compensate for the jejunum if needed.

空肠不同，肠可进行构和功能上的适应性改变，在必要时代偿空肠功能。

And finally at the end, running into the large intestine is the ileum, where important vitamins like A, B12, E, D, and K are absorbed.

最后，进入大肠的是肠，重要的维生素 A、B12、E、D 和 K 在肠中被吸收。

The third section is called the ileum, and it has tight intercellular junctions, allowing it to efficiently absorb fluid and begin concentrating the intestinal contents.

第三部肠，有紧密的细胞间链接，使得肠可以高效地吸收液体，浓缩肠内容物。

Occasionally, the diverticulum can invert and stick back into the intestine, allowing it to serve as a lead point that again drags the ileum into the cecum.

憩室偶尔会翻入肠腔内，成肠套叠的起点，把肠拽入盲肠。

This happens in the small intestine's lower regions, the jejunum and ileum, which are coated in millions of tiny projections called villi.

这发生在小肠的下部区域，即空肠和肠，它们被数百万个称绒毛的微小突起覆盖。

Extending from the end of the ileum to the anus, it is divided into four parts: cecum, colon, sigmoid colon and rectum.

大肠从肠末端延伸到肛门，并四个部：盲肠，肠，乙状肠和直肠。

As more gastrointestinal tissue is damaged, patients might experience pain in the affected areas, most commonly in the right lower quadrant which is associated with the ileum.

随着胃肠道组织损伤的加重，患者可能会在受损区域感到疼痛，最常见于右下腹，是肠的体表投射部位。
