The Digestive System Lab

During this lab we measured the length of our entire digestive system. For make it we took different length and color yarns and cut them by the right mesure for each of us. The fist step was to measure the mouth, the esophagus, the stomach, and both intestines and cut the yarns. When we had all we measured them in cm and right all this number in the data table. When we had all the yarns we tied them and took a photo of the real length of the digestive system. 

I had learn and realize how big is the digestive system, and I understood better how our body process the food.

The digestive system is able to fit inside the body because is bent several times, and is all together. The food spend an average of 53 hours to go through the entire digestive system, but I thought that was less, about 30 hours. The time that the food spend inside the large intestine is bigger that the one that I thought, and also depends the type of diet that you eat will be easier or harder to digest. The digestion is the breaking down the food in small pieces and the absorption is taking the nutrients, water, etc. needed. The organs hat are involved are the stomach, the small intestine and the large intestine.

I would like learn why do we barf when we are sick.
