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

小分三个部分，分别十二指、空与。

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

最后一部分末端，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）最后一部分的与大相连。

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

腔中散布着大量微小淋巴，称Peyer集合淋巴，以最多见。

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

与空不同，可进行构和功能上的适应性改变，在必要时代偿空功能。

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，进入大的是，重要的维生素 A、B12、E、D 和 K 在中被吸收。

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.

第三部分，有紧密的细胞间链接，使得可以高效地吸收液体，浓缩内容物。

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.

憩室偶尔会翻入腔内，成套叠的起点，把拽入盲。

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

这发生在小的下部区域，即空和，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.

大从末端延伸到肛门，并分四个部分：盲，，乙状和直。

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，是的体表投射部位。
