The intestines belong to the Digestive Tract (or Digestive System.) Fact: Stretched from end to end, the human intestines would stretch a mile, literally!
The digestive system is what converts regular food that we eat into useful form of nutrients which can be used by the rest of the body. Without these nutrients, the other organs would eventually shut down and die. The body does have the capability to convert energy from fat cells for use in the rest of the body. I'm not sure if this is a function of the digestive system, though.
Well, if your body is alive, all organs and tissues are alive. However, separate from the body, the digestive system would not function. Therefore, it cannot be said that the digestive system is "alive" apart from its functioning within the body.
It wouldn't be able to move!
you will not have enough blood cell cause they will die
you would need to put food up your asss
If the digestive system broke down, the muscular system would no longer receive nutrients. It would start to break down as well. The body would weaken, and tasks would become more difficult.
That would be pretty much any animal that's big enough for you to see with your naked eye.
Making a model of the digestive system will have to include a number of structures. Imagination will be necessary to find materials for the different organs. Sausage casings would make intestines in the model.
