Insulin is released in the postprandial phase (i.e. after eating meal) and leads to glycolysis and glycogenesis, as well as storing of triglycerides in hepatocytes.
Glucagon works on the opposite, slowing down storage of nutrients and increasing the level of glucose in the blood by upregulating glycogenolysis, inhibiting the Krebs' Cycle, and inhibiting glycogenesis. GLucagon does not have activity in the muscle cells, and is only active in the liver.
Those are the two main big players, though somatostatin, ghrelin, pancreatic polypeptide and CCK are also of great importance.
The autonomic nervous system can speed it up or slow it down,
but most of it is chemistry and proceeds at its own pace.

The activities of the digestive system are regulated by the contents of the digestive tract. The digestive tract is also called the gastrointestinal tract.

The purpose of the digestive system is to break down food to make it absorbable into the bloodstream.
Gastric acid secretion is regulated by hormones in the digestive system. This hormone, gastrin is secreted by the lining of the stomach.
The movement of food through the digestive tract is regulated by muscles. Muscles produce a narrowing which pushes the food through each of the digestive organs until it reaches the entrance of the stomach.
The activities of a cell are regulated by the nucleus.
The body system that the colon belongs to is the digestive system. The colon is also known as the large intestine.
