The large, hollow organs of the digestive system contain muscle that enables their walls to move.
The major hormones that control the functions of the digestive system are produced and released by cells in the mucosa of the stomach and small intestine.
These hormones are released into the blood of the digestive tract, travel back to the heart and through the arteries, and return to the digestive system, where they stimulate digestive juices and cause organ movement.

  Gastrointestinal tract Summary
However, because nutrient dispersal, by the digestive system itself to all cells of the body, was no longer feasible with such a specialized digestive system (and animals became larger and bulkier) a separate cardiovascular system evolved to serve that function.
The digestive system is that system which exists within all organisms to allow nutritive particles to be taken in, broken down, and either used by the body or removed from the body as waste.
The gastrointestinal tract or digestive tract, also referred to as the GI tract or the alimentary canal or the gut, is the system of organs within multicellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste.

 Gastrointestinal Carcinoid Tumor   (Site not responding. Last check: )
Gastrointestinal carcinoid tumors are cancers in which cancer (malignant) cells are found in certain hormone-making cells of the digestive, or gastrointestinal, system.
The digestive system absorbs vitamins, minerals, carbohydrates, fats, proteins, and water from the food that is eaten and stores waste until the body eliminates it.
The chance of recovery (prognosis) and choice of treatment depend on whether the cancer is just in the gastrointestinal system or has spread to other places, and on the patient's general state of health.

The gastrointestinal tract is governed by the autonomic nervous system, the nerve network that serves internal organs and works mostly without our thinking about it.
The autonomic system has two parts: the sympathetic nervous system, which activates in stressful situations; and the parasympathetic nervous system, the counterpart that promotes quiet activities (such as digesting your dinner).
When the sympathetic system is in charge, in essence, your gastrointestinal system turns off.
