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，血液停留在小血管内，基蜕膜是一个大的血液池。

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“母体层”，基蜕膜，就是一个整的血袋，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组织层散，在基蜕膜和胎儿静脉来回移动。

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）也是并发症一，由于基蜕膜层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。
