Differences Between Jejunum and Ileum
There is no line of demarcation between the jejunum and the ileum. There are, however, subtle differences between the two.
- The ileum has more fat inside the mesentery than the jejunum
- The ileum has a mesenteric and an anti-mesenteric vascular supply, while the jejunum has only a mesenteric vasculature
- While the length of the intestinal tract contains lymphoid tissue, only the ileum has abundant Peyer's patches, unencapsulated lymphoid nodules that contain large numbers of lymphocytes and other cells of the immune system.

Famous quotes containing the words differences between and/or differences:
“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts. The bond for normal twins, whether they are identical or fraternal, is based on how they, as individuals who are keenly aware of the differences between them, learn to relate to one another.”
—Pamela Patrick Novotny (20th century)
“What we have to do ... is to find a way to celebrate our diversity and debate our differences without fracturing our communities.”
—Hillary Rodham Clinton (b. 1947)
