“When we need to eat, our


                                        bodies give us signals”


                     The trip of food starts from the mouth

                   -  The mouth consists of teeth, tongue and


                       a liquid called “saliva”

                   -  At first, when the food enters our mouth

                       we start chewing the food using our teeth to

                       cut food into smaller pieces.


                   -  Saliva “liquid inside mouth” softens the food so we

                       can swallow it.

                   -  After swallowing, the food enter a tube that take


                       food to the stomach.




                     Then food enters the stomach

                   -  Stomach is a large muscular organ.


                   -  Inside the stomach there is a liquid

                       called “acidic juice”.

                   -  Acidic juice mixes with food to break


                       it down and get nutrients.





                      After the digestion, blood carries the nutrients to all

                   body parts to give them energy they need.
