Anything within the digestive system is still anatomically and physiologically considered "outside the body" until it undergoes absorption, therefore, anything inside any part of the digestive system and not touching the cilliary walls can be considered not connected to anything else.

I am just reading 'The Second Brain' and - lo and behold - there is the answer. Yes indeed, everything from the point of entry to the point of exit is considered outside of the body. It only becomes part of the body when it is absorbed.

I'm stumped. I can't find anything in research, and I know of nothing that isn't "connected" in the body. Even blood, which moves freely, is considered a form of connective tissue.

My anatomy and physiology textbook written by a medical doctor and registered nurse with Ph.D.s supports Austin's answer. "Food material in[the alimentary canal] is technically outside the body because the canal is open to the external environment at both ends."

Although all structures (anatomy) are connected by connective tissue, the hyoid bone in the throat is perhaps the most "free."
