Why does someone have to take a dump?

Answer 1

The digestive tract has many processes in digesting food, some of which begin in the mouth. Once food has entered the mouth, an enzyme in your saliva along with your teeth, help in initially breaking the food down. Once it is broken down to a point at which it can be swallowed, it enters the stomach. Powerful acids inside the stomach break the food down much more. Once it has been digested in the stomach, it passes through to the small intestine, which is very long. The digested food will travel the small intestine until it reaches the large intestine, or colon. All along on the journey, nutrients have been "sucked" out of the food and deposited into the body. However once entering the large intestine, moisture is what will now be "sucked" out of the digested matter. That is why you can get constipated if the matter is in your large intestine too long, or you can have diarrhea if it passes through too quickly. Once the digested matter has reached the end of the large intestine, or colon, it is ready to be ejected as waste matter. Thus, causing David to take a dump. By taking the dump, his body was getting rid of the waste matter it could not use. I hope that helps explain what you wanted to know and answer any questions you had. If you have any additional questions which I did not answer, or perhaps you would like to learn more about what happens inside the intestines, as I just went over it briefly, I would suggest Google-ing "The Digestive Process", or something to that degree.
