Separating liquids from solids in the old body.

[geordief]

Plead ignorance at this stage in my life but how dods this process happen in the body?

 

When I eat my meal there are both liquids and solids.

 

Clearly they are separated somehow.Does this occur in the stomach?

 

There can't be a  Trump recommended centrifuge down there so how does the process get started (are there a few stages ,perhaps?)

Water is absorbed passively throughout the intestine. The small intestine absorbs the bulk and then gets further removed as it moves through the large intestine.
