The accumulation of fluid in the peritoneal cavity is called ascites.

积存在腹膜腔里的液被称为腹水。

That should reduce the movement in your abdomen while you're exercising, meaning less strain on your ligaments and membranes.

那可以在运动时减少腹内官的移位，官之间的腹膜与韧带的拉扯。

我没看到流和腹膜腔的。

How do you know those things didn't rupture his peritoneum?

你怎么就知道这个手术就不会割裂他的腹膜?

The kidneys are located at the rear wall of the abdominal cavity just above the waistline, and are protected by the ribcage.

肾脏位于腹腔的后壁，刚好在腰部以上，由胸腔保护。They lie behind the peritoneum。它们位于腹膜的后面。

Kidneys are retroperitoneal, which means they lie between the dorsal wall and the peritoneum — the membrane that surrounds the abdominal cavity — rather than inside the cavity itself, like your intestines and stomach do.

肾脏位于腹膜后，这意味着它们位于背壁和腹膜之间——腹膜是包围腹腔的膜——而不是像你的肠胃那样在腔内。
