Eventually, the blood in the venous sinuses drains into the internal jugular vein and returns to the heart.

最终，静脉窦中的血流回流至颈内静脉，回流至心脏。

These veins travel through the arachnoid mater, pass through the subdural space and penetrate the inner layer of the dura mater to drain into the dural venous sinuses located between the two layers of the dura mater.

这些静脉穿过蛛网膜，经过硬膜下隙，穿过硬脑膜内层，使血液回流至两层硬脑膜中间的静脉窦中。
