- שקופית: 1
- Hi! My name is Mr. Sandwich, and I'm going to take you on a tour of the digestive system today.
- I started by entering the mouth, as you can see here. When you detect the delicious food approaching your mouth, your salivary glands begin to produce saliva even before the food reaches your mouth. As you chew, your saliva combines with mine to form a soft lump of food known as bolus.
- שקופית: 2
- The bolus is subsequently sent through the esophagus, a long, slender tube. The muscular walls of the esophagus press the bolus down to the stomach, our next destination.
- Once in the stomach, hormones tell the stomach walls to release acid that breaks down the bolus into a liquid called chyme. The hormones also alert the liver, gallbladder and and pancreas to start creating bile.
- From there, I enter the small intestine. The liver sends bile to the gallbladder, which holds it until I arrive. Tiny projections called villi absorb my molecules and the leftover fibre , water, and dead cells enter the large intestine.
- שקופית: 3
- Then, I go through the large intestine, or colon. The colon drains out most of the fluid through the intestinal walls. This leaves a soft mass called stool.
- The large intestine deposits me In a small pouch where I am held until I leave the body through the anus and this long journey through the digestive system, which takes about 30-40 hours, finally ends !

- The bolus then travels down a long, skinny tube called oesophagus. The oesophagus’s muscular walls squeeze the bolus down to the stomach, our next destination.
