The obliques function to pull the chest downwards and compress the abdominal wall. It also has some actions in both flexion and rotation of the vertebral column. The obliques contracting on one side can create lateral flexion on that side.
They assist in peristalsis in the digestive system. Working antagonistically, they contract and relax in turn to push ingested food down the digestive system.
In the stomach and ileum, they serve another purpose.
Within the stomach, these muscles churn food to assist in the mechanical breakdown of food. This, in turn, provides a greater surface on which enzymes can act. In the ileum, these muscles contact and relax, moving the villi in such a way as to maintain a high-to-low concentration gradient, so as more product is absorbed into the body.
Hope it helps, I've just leaned this at school, but its my interpretation. ^^
I did the answer, just made a profile. :P
Muscle in the human anatomy are often named by a characteristics they have like they may be the superior xxxx muscle or named for a structure they attach to. An Oblique muscle is just that a muscle that has attachements and a stanting angle just like an oblique in English (also known as a forward slash) /. Most people think of the "obliques" as the muscles in lateral walls of the abdomen but as they are named the internal and external oblique abdominal muscles but there are many more obliques all over the body. For example in the eye there are muscles called the superior and inferior obliqued which rotate the eye laterally and up or down.

The stomach is different from other organs of the digestive system because it has three layers of muscle in the muscular is externa. These are the inner oblique layer, the middle circular layer and the outer longitudinal layer.
Whereas the rest of the alimentary canal only has two muscular layers, longitudinal and circular, for peristalsis, the stomach has an additional oblique layer that permits it to churn and pummel the food.
The inner oblique layer of the muscularis mucosae.
because it has a third layer in the muscularis called the oblique muscle layer.
There are three muscular layers within the stomach (longitudinal, transverse and oblique) that act to turn over and mix the food.
It is actually four involuntary muscles. The longitudinal layer, circular layer and oblique layer of the muscularis externa and the pyloric sphincter

The wall of the stomach is structurally similar to other parts of the digestive tube, with the exception that the stomach has an extra oblique layer of smooth muscle inside the circular layer, which aids in performance of complex grinding motions.
The subdivisions of the wall layer muscularis externa are the longitudinal layer, circular layer, and oblique layer.
