Gastrointestinal tract
The digestive tube is an ambiguous term I have heard it used in reference to many things and so will attempt to name them all. The most common use of digestive tube is when someone is talking about the Esophagus. This is the tube that connects the Pharynx (the top part of the throat) to the top of the Stomach. It is clever in that it has a method of propulsion for the Bolus (food particle that is swallowed). The motion is caused by the part of the esophagus in front of the bolus relaxing and the part behind contracting to push the food along. This motion is called Peristalsis. Another common use of the digestive tube is when a person is referring the the entirety of the Gastrointestinal Tract (also known as the Digestive Tract). This includes everything from the oral cavity to the anus and as an overall function of breakdown and absorption of nutrients within food. A less common use, although perhaps the most valid, is when someone is referring just the Small Intestines. This is ironically much longer than the large intestine and is the tangled mess of tubing that sits at the bottom of the abdomen. In reality this, not the stomach, is where most digestion takes place and all the absorption of nutrients takes place. The majority of the digestive fluids are added to the small intestine in a section at the very start called the Duodenum (very short, only around 15cm) and most of the absorption takes place in the Jejunum and Ileum (much longer, around 8m) which eventually connects to the Large intestine. In short the "digestive tube" could be referring to 1)The Esophagus 2)The whole of the Gastrointestinal Tract or 3) The Small intestine. The term is however not a recommended one because of its ambiguity.
