Where does the digestive tract begins?

Well, I don't know If I really understand the question but the digestion begins when the food enters the mouth, that is when teeth start crushing (mechanical), and the tongue forms the food into a ball, and salaiva covers the food and softens it, so it can go through the oesophagus.

I hope I answered your question. =)
