DIGESTIVE SYSTEM


Let's discover where the food goes! 


What is digestion??


     - The digestive process involves breakdown of food from complex to simple form in the alimentary canal.


New terms: 


The digestion process involves:
       
a) Physical digestion: Mechanical process, breaking down food into smaller particles, by using the teeth.


b) Chemical digestionAction of various enzymes.The end  products are simpler molecules which are soluble.






So, can you guess what happen to the food?

   1) Digestion of carbohydrates starts in the mouth
   2) Digestion of proteins starts in the stomach
   3) Digestion of fats starts in the small intestine
   4) Digestion of carbohydrates, proteins and fats ends in the 
       small intestine

    I used to think that our food will be simply absorbed into the body, as whole !

  2. That's why i always mentioned in class, "What you eat is what your brain going to get". When our body absorbed the food (which involved lots of hard work), it will go into the blood system and eventually to the brain. So, eat good and healthy food for the BEST brain development!!!
