And then plants cannot pull enough water to survive.

然就不能吸收足够的水分来生存。

But some of your cells just can’t take on that much water.

但是你的一些细胞不能吸收那么多的水。

All right, so whatever isn't absorbed, like fiber, continues its journey onward through the ileocecal sphincter and into the very last part of the gastrointestinal tract: the large intestine, also known as colon.

那么，所有不能被吸收的质，如纤维素，将沿继续前进，通过回盲括约肌，进入的最一部分：大肠，也称之为结肠。

The main job of the gastrointestinal system is ingestion - taking in food, digestion - breaking it down into nutrients, absorption - pulling these nutrients into the bloodstream, and finally, excretion - getting rid of waste.

有四大功能：一是进食，即摄入食；二是，将食分解成营养成分；三是吸收，即把营养成分吸收入血液；四是排遗，即排出不能吸收的废。
