The Digestive Journey
טקסט Storyboard
- שקופית: 1
- Hi! My name is Stacy and I'm going to lead you on a journey through the digestive system! First, as you see here, I bite into my food. Your saliva glands will start pumping out saliva, before the food even reaches your mouth. As you chew, the saliva mixes with me to create a soft lump of food called bolus.
- שקופית: 2
- The bolus then travels down a long, skinny tube called the esophagus! The esophagus's muscular walls squeeze the bolus down to the stomach, our next destination!
- שקופית: 3
- 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 pancreas to start creating bile!
- שקופית: 4
- From there, the bolus enters the small intestine. The liver sends bile to the gallbladder, which holds it until it arrives. Tiny projectons called villi absorb my molecules and the leftover fiber, water, and dead cells enter the large intestine!
- שקופית: 5
- Then, the bolus goes through the large intestine, or the colon. The colon drains out most of the fluid through the intestinal walls. This leaves a soft mass called stool!
- שקופית: 6
- The large intestine deposits me in a small pouch where the bolus am held until the food leaves the body through the anus. And this long journey through the digestive system, which takes about 30-40 hrs, finally ends!
