SCIENCE Q4- ORSOLINO 8 FAITH
Storyboard Tekst
- Hey! My name is Ms. Orange and I'm going to lead you on a journey through the Digestive System! First, as you see here, I enter the mouth. You sense the yummy food coming into your mouth, so your saliva glands starts pumping out saliva. As you chew, the saliva mixes with me to create a soft lump of food called Bolus.
- 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.
- 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.
- 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 fiber, water, and dead cells enter the large intestine.
- Then, I go 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.
- 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 hrs, finally ends.
