Peristalsis
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
Peristalsis
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 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.
muscular system
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.
the skeletal and muscular system provide a benefit to the nervous system. without them, when your brain tells you to reach for a cup, those systems wont be there to physically do the action.
