The stomach has muscles that squeeze and mix food as well as acids that break it down. The stomach, then, performs both mechanical and chemical digestion.

If you are referring to the digestive system, I believe this would be the pyloric sphincter. After the stomach turns dry food into a wet mass, it delivers it to the duodenum via the pyloric sphincter (muscle).
Yes, the muscles squeeze the food through the digestive system :)

The stomach, or digestive system and/or digestive tract.
Chewing starts the process, stomach muscles continue the mixing.
they squeeze their wrists to achieve maximum contraction of the muscles in their arms when they pose-the muscles of the forearm and the biceps especially.PBB
Sounds like you're talking about Peristalsis (if you're looking for the actual name). Basically, as I understand it, the intestines have muscles that do two different things. One set is circular and contracts to basically squeeze the tube. The longitudinal muscles contract along the length of the intestine and help to propel the food onward. Everything happens in a wave-like motion with the circular muscles contracting to squeeze the food forward more and more and to prevent the food from being able to more backward, while the longitudinal muscles move the whole thing onward.
The digestive system includes muscles that squeeze the food in such a way as to drive it in the direction it needs to go; this is technically known as peristalsis.
