How many holes does a straw have?

[Mr.Obvious]

So The human body doesn't have any holes, technically speaking?

I had an MD explain to me that the human G.I. tract is a hollow tube through the body but not considered to be the inside of our body. If something is swallowed, such as poison or food, it is still outside our body until it enters the bloodstream.

Yeah, that was what I was getting at too, but less scientificky.
