Digestive System Facts Unfortunately, germs can stick to food dropped on the floor in less than five seconds. Every time you lick a stamp, you consume 1/10 of a calorie. If your stomach didn't produce a new layer of mucous every two weeks, it would digest itself. People eat more popcorn when watching a sad movie as compared to a happy one. Food can get to your stomach even if you are hanging upside down. The small intestine is about four or five times larger than the large intestine.

The small intestine can be as short as 4.6 m (15 feet) to as long as 9.8 m (32 feet). And here is a picture of a pig’s digestive system:

White Bread Challenge

Now we will review a few important ideas Pay really good attention during the review or the next assignment you have will be difficult.

Review Remember that the digestive system’s functions happen in this order: – Ingestion (eating) – Digestion (smashing the food down) – Absorption (getting the nutrients from the food) – Elimination (getting rid of the waste)

Review The food goes through the digestive system’s organs in this order: – Mouth – Esophagus – Stomach – Small intestine – Large intestine

Digestive System Stories By yourself or in a group of up to three people, you will write a story about a piece of food’s journey through the digestive system. You have to pick a certain type of food and write the story from the point of view of the food. – Example: I’m a slice of pepperoni pizza from Papa Johns. One day I was created in a very hot oven and delivered to some hairy dude’s house. After licking his lips, the hairy man chomped down on my crust! …

Digestive System Stories Your food has to go through ingestion, digestion, absorption, and elimination. You must mention each part of the body it travels through and what happens in each part of the body. Your story should be creative and the info on the digestive system must be accurate. Near the end of the hour we will read several stories and vote on the best one. The winners will get a prize next time they are in class.
