Re: Is everyones intestine colied the same?

That’s a really interesting question!  The answer is no, not all intestines
are coiled the same way.  There is actually a lot of variation that can
occur during development of the intestines that can all lead to normal
functioning intestines.  Understanding the developmental process that
occurs can help clarify how this variation occurs.  An overview of
intestinal development can be found at this website, with some animations:

The gut is held in place generally by the mesentery, which contains the
arteries, veins and nerves that connect to the gut.  Connections to the
other abdominal organs also ensure that the gut is roughly in the right
place.  So overall, the location and general architecture of the gut and
the abdominal organs are the same in all normal individuals.  The smaller
scale coiling and twisting can be different, as long as the functions can
be maintained.  This variation is similar to most other types of variation
in anatomy of humans.  As long as the functions are preserved, quite a bit
of variation can exist without any major consequences.   

However, some variations are more serious, and can lead to complications
and illness.  One such complication is malrotation.  An anatomical drawing
of this can be found on Netter Medical Illustration’s website:

This is a condition in which the rotation of the intestines during
development does not happen the way it should, and it leads to problems in
digestion because food cannot pass through the intestine as well or at all.

I hope this answers your question.  Good luck with your biology class!
