These villi push into the decidua basilis, like tiny fingers reaching into a warm pool of oxygen-rich maternal blood.

这些绒毛伸进基蜕膜内，像手指伸入温暖的氧含丰富的母血池中。

But unlike other parts of the circulatory system where blood stays within narrow blood vessels, the decidua basalis is a huge pool of blood.

但不同于循环系统的其他部分，即血液停留在小血管内，基蜕膜一个大的血液池。

The maternal layer, the decidua basalis, is literally a flattened out bag of blood with uterine arteries delivering blood in and uterine veins pulling blood out.

所谓“母体”，即基蜕膜，就一个平整的血袋，将子宫动脉的血输送进去。

Gases and nutrients move back and forth between the decidua basalis and the fetal veins, by diffusing through the tissue layer of the thin chorionic villi.

气体和营养物质通过在薄绒膜绒毛之间扩散，在基蜕膜和胎儿静脉之间来回移动。

Also, disseminated intravascular coagulation, or DIC, is also a possible complication, since the decidua basalis layer is also rich in thromboplastin, so an abruption causes the release of large quantities of thromboplastin which causes widespread clotting.

还有弥散性血管内凝血（DIC）也并发症之一，由于基蜕膜内富含促凝血酶原激酶，所以胎盘剥离导致促凝血酶原激酶大量释放，从而导致广泛的凝血。
