The duodenum is the first part of the small intestine that connects to the stomach. It plays a crucial role in the digestion process by receiving partially digested food from the stomach and mixing it with digestive enzymes from the pancreas and bile from the liver. The duodenum absorbs nutrients and further breaks down food before it continues into the rest of the small intestine for further digestion and absorption.
