It all begins when we ingest a piece of food like an apple the chew'd up apple goes through the oesophagus where it does a technique known as peristalsis. Peristalsis is when the body moves food by a movement. after the oesophagus its the stomach, that where digestion starts. when the food lands in the stomach it gets absorbed by the acid leaving the waste behind then it travels to the liver. the liver produced a liquid that smells called bile . the bile breaks the food even more and makes it more slippery to pass.
when its done the lower intestine breaks down even more nutrients from the fecal material which takes the energy to the bloodstream. and finally the large intestine where bacteria called E-coli break the rest of the energy and it get ejected into the toilet
