Sign in to saveAlso known as proximal small intestine
The duodenum is the first section of the small intestine in most vertebrates, including mammals, reptiles, and birds. In mammals, it may be the principal site for iron absorption. The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine.
The duodenum is the first and shortest section of the small intestine, located before two other sections called the jejunum and ileum. In mammals, it may be the principal site where iron is absorbed from food into the body.

十二指肠（拉丁語：Duodenum）是多数高等脊椎动物的小肠起始段，有时候也称为前肠或近侧小肠。十二指肠是小肠最短的部分，之后是空肠和回肠。人类的十二指肠长约25－38厘米。 从十二指肠球部起始，至十二指肠悬肌结束，可分为上部（球部）、降部、水平部和升部。十二指肠包绕胰头，并固定于腹腔后壁。而十二指肠大乳头则是肝胰壶腹的开口处。 哺乳动物、爬行动物和鸟类拥有十二指肠，鱼类的十二指肠则不明显。哺乳动物的可能是吸收铁元素的主要部位。人类的十二指肠向左，动物的则朝前开口。
