Answer 1

The small intestine or small bowel is the part of the gastrointestinal tractbetween the stomach and the large intestine, and is where most of the end absorption of food takes place. The small intestine has three distinct regions – the duodenum, jejunum, and ileum. The duodenum is the shortest part of the small intestine and is where preparation for absorption begins. It also receives bile and pancreatic juicethrough the pancreatic duct, controlled by the sphincter of Oddi. The primary function of the small intestine is the absorption of nutrients and mineralsfrom food, using small finger-like protrusions called villi.
