We use our teeth and saliva to cut food into pieces, which then travels down the esophagus into the stomach where it mixes with gastric juices. In the small intestine, food further dissolves with pancreatic, liver, and intestinal juices and our body absorbs nutrients into the bloodstream. Remaining waste then moves into the large intestine where water is absorbed before final waste is expelled through the anus.

1.  With our teeth and with the help of saliva we cut food into small pieces.
 Food goes down the oesophagus.
 In the stomach food mixes up with liquids and gastric juice.
 The food dissolves in the small intestine with juices from the pancreas, liver
and intestine. Then, our body absorbs nutrients from the small intestine that
go to the blood.
 Large intestine absorbs water and waste products ( fibre and older cells)
remains there.
 Finally waste products are pushed out through the anus.
