Editing Jejunum (section)

==Function==
The lining of the jejunum is specialized for the absorption by [[enterocytes]] of small nutrient particles which have been previously digested by [[enzymes]] in the [[duodenum]]. Once absorbed, nutrients (with the exception of fat, which goes to the lymph) pass from the enterocytes into the [[enterohepatic circulation]] and enter the [[liver]] via the hepatic portal vein, where the blood is processed.<ref>{{cite journal|last1=CRANE|first1=RK|title=Intestinal absorption of sugars.|journal=Physiological Reviews|date=Oct 1960|volume=40|issue=4|pages=789–825|pmid=13696269|doi=10.1152/physrev.1960.40.4.789}}</ref>
