Duodenum (noun)

The first part of the small intestine, extending from the stomach to the jejunum.

Origin:

The term 'duodenum' comes from the latin word 'duodenum' which means 'twelve,' referring to the number of inches its length was once thought to be.

Examples:

1. The duodenum is responsible for the initial stage of digestion and the absorption of nutrients.
2. The small intestine, including the duodenum, is an important part of the digestive system.
3. The duodenum plays a crucial role in the breakdown of food and the release of digestive enzymes.
4. An irritation or inflammation of the duodenum is a common cause of digestive discomfort.
5. The duodenum, along with the other parts of the small intestine, is lined with tiny finger-like projections called villi that help to absorb nutrients.
