The subdural space plays a major role in venous blood drainage in the brain.

硬膜下隙在大脑静脉回流中起重要作用。

The chylomicrons slowly make their way up into the thoracic duct and get dumped into the venous blood.

乳糜微粒缓慢地上行进入胸导管，并被注入静脉血。

Venous blood oozes its way back.

所以静脉血缓慢地流回心脏。

When this happens, venous blood accumulates in the hepatic portal system, causing pressure to rise above 12 mmHg, which defines portal hypertension.

当这种情况发生时，静脉血会在肝门脉系统里蓄积，导致压力上升到12mHg以上，这就是门静脉高压症的定义。

Here, venous blood warmed up by the shark's working muscles passes right next to arteries carrying cold, oxygen-rich blood from the gills.

称之为细脉网在这里，被工作肌群变暖的静脉血。

So venous blood accumulates downward from the obstruction, causing features like ascites, esophageal varices and bleeding, Caput Medusae, diminished liver function and an enlarged spleen.

因此静脉血从阻塞处向下累积，引起诸如腹水、食管静脉曲张和出血、海蛇头、肝功能下降和脾脏肿大等特征。

The lymphatic vessels direct lymph toward the upper chest, where they finally return to the venous blood system through one of two large ducts.

淋巴管将淋巴管引向上胸部，最后它们通过两条大导管之一，返回静脉血液系统。

That's because the diaphragm muscle lowers during inspiration, and that creates negative pressure in the chest to bring in air, and that negative pressure also brings a bit more venous blood back to the right atrium and right ventricle.

这是因为吸气时膈肌下移，胸腔内的负压将空气吸入；这个负压同时将一些静脉血倒吸回右心房和右心室。
