The pyloric sphincter
The iliocecal sphincterThe ileum is the last (and longest) portion of small intestine. It empties into into the cecum (the first part of the "large intestine") at the iliocecal junction. The iliocecal sphincter is a ring of invountary smooth muscle at this junction, controlling the passage of digestive contents from the small intestine to the large intestine.

smooth muscle pushes food through the intestine and smooth muscle is a involuntary muscle
Your intestines contain a medial layer of smooth muscle. When the smooth muscle in your intestines is innervated this causes contractions of those smooth muscles. This action then propels food through the intestines. This is called peristalsis. So, as far as I know there are no other muscle groups that aide in digestions. There are however, a plethora of chemicals and enzymes that assist in the digestive process.

This is smooth muscle. It produces a wave of movement.
The muscle associated with the intestine is primarily the smooth muscle, which is responsible for peristalsis—the rhythmic contraction that moves food through the digestive tract. Additionally, the circular and longitudinal layers of smooth muscle in the intestinal walls facilitate digestion and absorption. In the context of the large intestine, the taeniae coli, a band of smooth muscle, helps in the formation of haustra, or pouches, in the colon.
Smooth muscle is found in your internal organs and one of the things it controls is digestion...
The ring like muscle that controls the flow from the stomach to the small intestine is called the pylorus or the pyloric sphincter. It is divided into two parts: the pyloric antrum which is connected to the body of the stomach and the pyloric canal which is connected to the beginning of the small intestine (the duodenum).
