where is the duodenum located in the human body
Duodenum The duodenum [help 1] 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.[5] In mammals the duodenum may be the principal site for iron absorption.[6]
Duodenum The first part, or superior part, of the duodenum is a continuation from the pylorus to transpyloric plane . It is superior to the rest of the segments, at the vertebral level of L1. The duodenal bulb about 2Â cm long, is the very first part of the duodenum and is slightly dilated. The duodenal bulb is a remnant of the mesoduodenum, a mesentery which suspend the organ from the posterior abdominal wall in fetal life.[9] The first part of the duodenum is mobile, and connected to the liver by the hepatoduodenal ligament of the lesser omentum. The first part of the duodenum ends at the corner, the superior duodenal flexure.[8]:273
Liver The liver is a vital organ only found in vertebrates.[2][3] In humans, it is located in the upper right quadrant of the abdomen, below the diaphragm. The liver has a wide range of functions, including detoxification of various metabolites, protein synthesis, and the production of biochemicals necessary for digestion.[4] It also plays a role in metabolism, regulation of glycogen storage, decomposition of red blood cells and hormone production.[4]
