How long is your digestive system?

In this lab I made a model of my own digestive system by measuring and cutting  yarn to represent lengths of different parts of the system, and tapping the pieces of yarn together to form one long string.

Digestive Organ	Color and Length (CM)
Mouth	12 cm
Esophagus	22 cm
Stomach	16 cm
Small Intestine	648 cm
Large Intestine	162 cm
Total	860 cm

My digestive system is almost 5.3 times my height but my it is able to fit inside my body because the small and large intestine is folded to increase surface area, which increases the number of reactions needed to break down food. 

I guess it takes 6-8 hours on average for food to move through your entire digestive system. According to MayoClinic, my guess is right in that it does take 6-8 hours on average for food to move through your entire digestive system. There are many factors that influence the time it takes. The complexity of foods, such as the structure and the components of the food, affect the time it takes. For example a juice will digest faster than a salad. Fat takes the longest to digest from of all the possible food macronutrients, because the liver can only produce a certain amount of bile to break down the fats per hour. 

Digestion is the mechanical and chemical breaking down of food into smaller components that can be absorbed into a blood stream. The mouth, pharynx, esophagus, liver , gallbladder, pancreas, and stomach help in the digestive process. 

Absorption takes place in the small intestine where most of the nutrients from ingested food are absorbed. The small and large intestine are responsible for most of the absorption. 

What are some disorders/diseases related to the digestive system other than diabetes? What happens if one of the organs fails to function? What are the chemical components of the fluids (enzymes, such as in bile and amylase) that help breakdown the macromolecules in food?
