The muscle action that mixes chyme with digestive juices throughout the digestive system is called Peristalsis. Peristalsis are wave-like of contractions and expansions of muscles. The muscles help to move the bolus (food) through the digestive tract. Peristalsis are located all over the digestive tract.

Peristalsis who ever asked this is an idiot just look it up on the internet or in a book

Gravity is not necessary for the function of the human digestive system. Food is moved through its entirety by muscular action, beginning with the tongue (which pushes food to the back of the throat) and proceeding with the oesophagus itself.
I can see that you think that gravity will pull it down. However food is moved through the digestive system by muscular action (called peristalsis) not gravity. Therefore it does not matter which way up an animal is.
The stomach is a muscular organ located in the upper abdomen. It stores and breaks down food through muscular contractions and the action of digestive enzymes. The stomach also secretes acid and enzymes to aid in the digestion process.
The muscular system uses the bones for their action. Without bones muscles would be useless at distance. Bones act like lever arms to increase the force produced by muscles. The digestive system gives nutrients to the muscles.
Segmentation is a muscle action that mixes chyme with digestive juices, while Peristalsis is a muscle action that moves food through the digestive system.
Peristalsis.
Peristaltic action is required by humans and similar animals which ingest and digest their food supplies in similar fashion. It is a pattern of muscular action along the intestinal walls and other parts of the digestive and excretory systems. The muscular action comprises "squeezing" of the contents so that they pass along the flexible, tubular intestine, whilst the other action creates lengthening and shortening of the "tube". This causes the contents of the "tube" to be passed along and ultimately excreted when you "have to go" to the toilet. As to what would change, that's a very theoretical question, the short answer to which is "they would die out", but this will not happen because natural development of species has designed the human body to work far more cleverly.
The process by which smooth muscle in digestive organs squeezes food through the digestive tract is called peristalsis. This wave-like contraction moves the food along the esophagus, stomach, and intestines, facilitating digestion and absorption. Peristalsis is an involuntary action controlled by the autonomic nervous system, ensuring that food is transported efficiently through the digestive system.
