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，即液停留在内，基蜕是一个大的液池。

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“母体层”，即基蜕，就是一个整的袋，将子宫动脉的输送进去。

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毛组织层之间扩散，在基蜕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.

还有弥散性内凝（DIC）也是并发症之一，由于基蜕层内富含促凝酶原激酶，所以胎盘剥离导致促凝酶原激酶大量释放，从而导致广泛的凝。
