digestion
Öykü Penceresi Metni
- 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.
