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。

Gonadotropin-releasing hormone is released into the hypophyseal portal system, which is a network of capillaries connecting the hypothalamus to the hypophysis, or pituitary.

促性腺激素释放激素（GnRH）释放到垂体门脉系统，后者是一个将下丘脑与垂体互相连通的毛细血管网。

The round ligament stay shut because pressures in the portal venous system and the systemic venous system are the same under 12 mmHg.

圆韧带保持关闭状态，这是因为门静脉系统里的血压和体静脉系统的血压都同样是低于12mmHg的。

All right, as a quick recap, portal hypertension is when the pressure in the hepatic portal system is greater than 12 mmHg.

得！快速回顾一下：门静脉高压症是指肝门系统压力大于12mmHg。

This happens because blood flow follows the path of least resistance and shunts away from the portal system and towards the systemic system of circulation.

血流循着阻力小的方向进行，因为门静脉高压，所以会绕过门静脉系统分流至体循环系统。

Portal hypertension leads to the formation of Portosystemic shunts, which is when blood is diverted away from the portal venous system and backs up into the systemic veins.

门静脉高压症可导致门脉-体静脉系统分流的形成，即血液从门静脉系统转向分流，回到了体静脉系统。

Second, blood backing up in the systemic veins leads to portal systemic shunts, which happens in the three points where the systemic venous system and hepatic portal system are connected.

其次，淤积在体静脉的血液造成门脉-体静脉系统分流，发生在三个部位，即体静脉系统与肝脏门脉系统相连接的地方。
