And then plants cannot pull enough water to survive.

然后植物就不能吸收足够的水来生存。

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，所有不能被吸收的物质，如纤维素，将沿消化道继续前进，通过回盲括约肌，进入消化道的最后一部：，也称之为结。

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.

消化道有四功能：一是进食，即摄入食物；二是消化，将食物解成营养成；三是吸收，即把营养成吸收入血液；四是排遗，即排出不能消化吸收的废物。
