Examples from the Web for midgut
Midgut, closely associated at its beginning with the liver and pancreas.
This type is prevalent in amphibia and fish (Fig. 112, distal segment of midgut).
The midgut forms a simple loop with a descending and ascending limb closely bound together by mesenteric attachment.
In all forms in which the gland is found it is connected with the post-gastric intestine and marks the beginning of the midgut.
The midgut is usually the longest portion of the intestinal tube.
