It is supplied by both superior and inferior mesentric artery so in case of hypotension its the most prone area to undergo ischemia..

because it does not have its own blood supply..it receive blood from the terminal branches of both the arteries..so in case of hypotension,it will become deprived of the bloodsupply and undergo ischemia..

yeah you are right but i think that the area between SMA and IMA is in Transverse colon ..Upper 2/3 by SMA and lower 1/3 by IMA and the area between these two is also prone to ischemia..
Now i am confused..

DR.james told us JUST to remember SPLENIC FLEXURE as most prone to ischemia...if we go more deep in anatomy though not bad but not so good as well..cuz there is no concept.. just memorization..save time and spend on other things

The splenic flexure is the junction between the regions of mid gut and hind gut. And that is why they have different arterial supply. They were formed from different group of arteries.
Hence, later on embryologically speaking, when the GIT formed the anastamoses happened but it is very poor compared to anastamoses amogst the invidual arteries of midgut and hindgut in themself.
And due to this, That region is more prone to ISCHEMIA.

Thumbs Up ..

I will go with splenic flexure.
The splenic (or left colic) flexure is a sharp bend between the transverse and the descending colon in the left upper quadrant of humans.
