Anus
Food does not go 'Inside' of your digestive system. It remains 'Outside' of the digestive system. So most of the digestion is extracellular. So from mouth to anus the entire digestive system is connected to the 'Exterior' and is not technically and immunologically 'Inside' your body.
Technically due to the digestive system being one long tunnel that runs from your mouth to your anal cannal, and doesnt need to be cut open to be reached, it is therefore the outside of your body.
You should consider if inside of the digestive tract is made up of cells. organs or systems that have hollow tube such as mouth, respiratory tract, digestive system, and GI tract are considered external environment because it is connected to outside. You can think of more examples of the external environment in the body.
All openings of the body that led to the outside are moist with mucus. This includes the mouth and the rest of the digestive tract, the respiratory tract (including the nasal passages), the urinary tract and the reproductive tract. This mucus keeps the tracts from drying out. If they would dry out, microbes could get into the body and cause an infection. The mucus also produces easy passage of products into and out of them.
