Digestive system overview the digestive system takes in food, breaks it down (digests), sends the usable parts off into the blood and gets rid of the waste there are many organs involved in the digestive system.
The digestive process (1) - the four basic stages of ingestion, digestion, absorption-assimilation, and elimination part of a series of pages about the digestive system, including the organs of the digestive system, and the processes by which foodstuufs are broken-down and processed by the human body. The pancreas is an organ located in the abdomen it plays an essential role in converting the food we eat into fuel for the body's cells the pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar location of the pancreas.
