Question

write the short note on duodenum ​

Answer 1

Answer:

The duodenum is a shortstructure ranging from 20 cm (7.9 inches) to 25 cm (9.8 inches) in length, and shaped like a "C". It surrounds the head of the pancreas. It receives gastric chyme from the stomach, together with digestive juices from the pancreas (digestive enzymes) and the liver (bile).

Answer 2

__________________________

The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds.

In fish, the divisions of the small intestine are not as clear, and the terms anterior intestine or proximal intestine may be used instead of duodenum

In mammals the duodenum may be the principal site for iron absorption.

The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine.
