Peristalsis - the moving of food along through the digestive system.
peristalsis
As a simplified response, muscles in the tongue pushes food into the pharynx. However, it's a little more complicated than that. This address has good info on your question: http://www.nature.com/gimo/contents/pt1/full/gimo1.html
This is the movement of the intestines caused by the smooth muscle and it causes chyme (partially digested food) to move along the length of the intestine.
Peristalsis.
Peristalsis is a series of involuntary smooth muscle contractions along the walls of the digestive tract that move food through the digestive tractperistalsis
Peristalsis - the moving of food along through the digestive system.
Peristalsis is the process by which smooth muscle moves a mass of food (called the food bolus) through the digestive system. There is circular smooth muscle and longitudinal smooth muscle in the digestive tract. Contraction of circluar smooth muscle keeps the food bolus from moving "backward" along the digestive tract by decreasing the diameter of the tract behind the bolus. Contraction of the longitudinal muscle in the digestive tract propels the food bolus "forward" in the digestive tract.
Peristalsis involves circular smooth muscles and longitudinal smooth muscles in the effort to produce waves of contractions in a tube. This process is used in digestion to move the food (bolus) through the esophagus and the chyme (partially digested food) through the intestines.
Peristalsis. This process moves ingesta along the digestive tract.
no MyocardiumThere are three types of muscle: skeletal muscles which move the bones, smooth muscle which produces waves (peristalsis) along a tube. For example, the digestive tract and muscle found only in the heart. This is called myo- (muscle) -cardium (heart).
Smooth muscle is not striated and is not under voluntary control. Your digestive system contains smooth muscle that is involuntary, which causes the digested food to move along the digestive tract in a motion called peristalsis.
peristalsis is basically the contraction and relaxation of muscle in digestive system which moves food along. for example if you have a staw with a drop of liquid in it, and you squeeze the straw just behind the liquid (this representing the muscular contraction), then the liquid will move away from where you are squeezing. so by the continuous contraction and relaxation of muscles in the walls of the digestive tract, movement of the food occurs. hence, the purpose of peristalsis is the movement of food along the digestive tract.
Peristalsis. The process of peristalsis begins in the esophagus when a bolus of food is swallowed.
