The duodenum is the first segment of the small intestine, and the stomach releases food into it. Food enters the duodenum through the pyloric sphincter in amounts that the small intestine can digest. When full, the duodenum signals the stomach to stop emptying.
What are the three parts of the small intestine and their functions?

- The duodenum is the first section of the small intestine and is the shortest part of the small intestine. It is where most chemical digestion using enzymes takes place.
- The jejunum is the middle section of the small intestine.
- The ileum is the final section of the small intestine.
What is the small intestine in the digestive system?
How big is the small intestine in relation to the stomach?
The small intestine is only about 3.5cm in diameter, hence the name ‘small’, and it lies in the central and lower abdomen. Food moves through it relatively slowly, over a period of hours, allowing time for the actions of digestion and absorption for which this part of the GI tract is designed.
What makes up the lower GI tract of the body?
The lower GI tract consists of the large intestine and the anus. The large intestine absorbs water and changes the waste products of the digestive process from liquid into formed stool. The large intestine includes the appendix, a finger-shaped pouch attached to the cecum
