| HORMONE | PURPOSE | ACTION |
| Insulin | Regulate blood glucose (sugar) in the normal range | Forces many cells of the body to absorb and use glucose thereby decreasing blood sugar levels |
| Glucagon | Assist insulin in regulating blood glucose (sugar) in the normal range (actions are opposite of insulin) | Forces many cells of the body to release (or produce) glucose (increasing blood sugar) |
| Somatostatin | Regulate the production and excretion of other endocrine hormones | Slows down production of insulin, glucagon, gastrin, and other endocrine hormones |
| Gastrin | Assist in digestion within the stomach | Induce acid producing cells of the stomach to produce acid |
| Vasoactive Intestinal Peptide (VIP) | Help control water secretion and absorption from the intestines | Causes intestinal cells to secrete water and salts into the intestines (inhibit absorption) |
The chart above helped me with the pancreas aspect because the only thing I saw to relate the endocrine and digestive system was the pancreas. By doing some research I found out that a whole system of endocrine cells can be found in the GI. Their hormones stimulate, for instance, the production of digestive juices. In the stomach, gastrin is secreted which stimulates the production of hydrochloric acid. Like I stated before the only like structure or organ that I can see is the pancreas. The job it does for the endocrine system is that it releases insulin by the beta cells and glucagon by the alpha cells. The job it does for the digestive system is that it is the source of powerful digestive enzymes required to chemically break down fats, carbohydrates and proteins. It also secretes another substance to help neutralize stomach acid.
