Editing Jejunum (section)

==History==

===Etymology===
''Jejunum'' is derived from the [[Latin]] word ''[[wikt:ieiunus#Latin|jējūnus]] (iēiūnus)'', meaning "[[fasting]]." It was so called because this part of the [[small intestine]] was frequently found to be void of food following [[death]],<ref>{{cite web|last1=Harper|first1=Douglas|title=jejunum|url=http://www.etymonline.com/index.php?term=jejunum|website=Etymology Online|access-date=15 November 2014}}</ref> due to its intensive [[Peristalsis|peristaltic]] activity relative to the [[duodenum]] and [[ileum]].
<!-- Editors: The contributor intentionally used this variant ("jējūnus") so that the origin of the word is clearer, and many sources cite this variant. Do not change to "iēiūnus". -->

The [[Early Modern English]] adjective ''[[wikt:jejune|jejune]]'' is derived from the same root.<ref>{{cite web|url=http://www.oed.com/view/Entry/101004?redirectedFrom=jejune#eid|title=Oxford English Dictionary: jejune, adj.}}</ref>
