And in turn, each villus is covered in teeny tiny little microvilli.

每个绒上又分布有大量微小的微绒。

By analyzing the villi that provide contact with the mother's blood to the fetal membrane, Muneta deduced that the fetus must be living in an environment of elevated ketones from the start of pregnancy.

通过分析在母体血液和胎膜之间起着纽带作用的绒，Muneta 推导出，在母体受孕之，初胎儿便生活在一个酮体水平较高的环境中。

These folds are lined with tiny hair-like villi and even tinier microvilli, which create a truly impressive surface area — large enough that, if it were unfolded, it would cover a tennis court.

些褶皱内衬着微小的绒，甚至小的微绒，造了一个真正令人印象深刻的表面积——足够大，如果展开，它将覆盖一个网球场。

This can also be done prenatally by testing fetal DNA obtained through either chorionic villus sampling or amniocentesis.

可以在产前通过检测胎儿DNA完成，如绒膜绒取样或羊膜穿刺术。

He actually has, I think it's like in the second volume of his classic book on the histology of the nervous system, one of the last figures talks about like the innervation of the villi in the intestines.

他在其经典着作《神经系统组织学》的第二卷中，最后一幅图讨论了肠道绒的神经支配问题。

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

一过程生在小肠的下部，即空肠和回肠， 其内壁覆盖着数百万个微小突起， 称为绒。

It is through the capillaries in the villi that completely digested nutrients pass into the bloodstream and lymph vessels.

通过绒中的细血管被完全消化的营养物质进入血液和淋巴管。

Another example can be found in your small intestine, where structures called villi fold up into little fingers.

另一个例子可以在你的小肠中找到，那里有一种叫做绒的结构， 它们像小手指一样折叠起来。

Each villus is made of cells with highly folded membranes that have tiny bumps called microvilli to increase their surface area.

每个绒由细胞构成，些细胞的膜高度折叠，上面布满了称为微绒的小突起，以增加其表面积。

In the wall of the entire small intestine are millions of tiny, microscopic projections called villi (villus).

在整个小肠的肠壁上有数百万微小的微观的结构称为绒（绒）。
