Hii I am Mr.Apple.Today I will take you to journey of digestive system.When I enter the mouth the salivary glands start secreting saliva .As you chew saliva mixes with me to form a soft lump of food called bolus.
The Bolus then move down a long tube called oesophagus.The peristaltic movement of oesophagus squeezes food bolus to my next destination called Stomach
Inside the stomach the food is broken down into liquid called chyme which mixes with gastric juices
From there I enter the small intestine. The liver send bile juice to gall bladder which holds it untill I arrive .Tiny finger like projection called villi absorb my molecules. Useful nutrients are taken by blood to all parts of the body. The leftover fiber and water enter large intestine.
All the left over waste is compacted and stored at the end of large intestine called rectum. Water and other fluids are extracted here from faeces.
The waste then passes out of the body through an opening called anus .And this long journey the digestive system finally ends.
