Placental abruption happens when there is a separation of the uterine wall and decidua basalis.

当子宫壁和基蜕分离时，就发了胎盘早剥。

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，手指伸入温暖的氧含丰富的母血中。

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

但不同于循环系的其他部分，即血液停留在小血管，基蜕是一个大的血液。

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绒毛组织层之间扩散，在基蜕和胎儿静脉之间来回移动。

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“母体层”，即基蜕，就是一个平整的血袋，将子宫动脉的血输送进去。

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.

还有弥散性血管凝血（DIC）也是并发症之一，由于基蜕层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。
