THE DIGESTIVE SYSTEM LAB

1.     In this activity we got some white string and 4 other colorful pieces of ribbon. The goal of this project was to make a measurement of your digestive tract. We had to measure how tall we were, our finger span, the span from our lip to the end of our jaw line. In the final product we should have ended with things long string that should be about the size of our digestive tract because everyone’s tract is different based on the measurements you got above.

DIGESTIVE ORGAN	COLOR and LENGTH (CM)
Mouth	RED 14.75
Esophagus	BLUE 47
Stomach	GREEN 18.5
Small Intestines	WHITE 619.76
Large Intestines	SHINNY BLUE 136
TOTAL	836.01

2.     The length of your digestive system is similar to your height but it’s just about 4x the size. I think the digestive system that I made would fit almost perfectly saying that I made the measurements properly.

3.     I think it would take about 3-4 hours for food to move completely through my digestive tract. When I looked online the average time it takes for food to move through someone’s digestive system is 6-8 hours. It varies on how much you eat. According to LIVESTRONG, the more fiber you eat it will move though your tract quicker, Caffeine tends to slow down your digestive system as well as some drugs whether it is prescription or not. Your food will also pass through your system quicker with physical activity.

4.     Digestion is different from absorption in that digestion is the breaking down of food where absorption is when the body absorbs nutrients. Absorption is in the small intestines, and digestion is in the stomach.

5.     Other questions I have about the digestive system are sometimes after we eat food and it doesn’t sit well with us we feel the urge to throw up. My question is what makes us throw up?
