Gastrointestinal System
When is it considered that food material is outside of the body?
When in extracellular fluid
When outside of a body cavity
When urinated or defecated out
When part of the contents of the gut
When part of the contents of the gut
Food in the gut has not “entered the body” until it has been absorbed into the epithelial lining. This happens after being hydrolysed into molecules that are small enough to be absorbed. The material that is urinated or defecated out is indeed outside the body, but is not considered to be food.
