What happens if peristalsis is too slow?
Slow transit constipation is characterised by the reduced motility of the large intestine, caused by abnormalities of the enteric nerves. The unusually slow passage of waste through the large intestine leads to chronic problems, such as constipation and uncontrollable soiling.
What causes peristalsis to stop?
Typically, muscles in the intestines contract and relax to cause a wave-like motion called peristalsis. This movement helps food travel through the intestines. When an ileus occurs, it stops peristalsis and prevents food particles, gas, and liquids from passing through the digestive tract.

What Is the Peristalsis?
Peristalsis is a series of muscle relaxations and contractions that occur in the lining of the intestinal tracts. This procedure makes it possible for waste and food products to be pressed through the intestines. Sometimes, it is in fact possible to feel these muscular contractions as they take place. This is specifically common for the large intestinal tracts. Peristalsis is just possible since the human digestive system is adapted to peristaltic pumps. These are muscular devices that utilize the same strategy as those used by the system to press fluids through the body.
How does the gastro-intestinal tract work?
In this procedure, when water or food enters the gastro-intestinal tract, the muscles in this tract relax and compress in a motion that is wave prefer to allow the material to go through. For instance, when you swallow an apple, smooth muscles in the esophagus relax and contract to allow the apple to pass through. The contracted muscles permit the material to pass to the area with unwinded muscles lower in the esophagus. This continues until the food reaches the stomach. The muscles above stay contracted to avoid the food from flowing back.

The circular and longitudinal muscles contract and relax, leading to the peristaltic movement. When there is a bolus of food, circular muscles behind the bolus contract and relax in the front, whereas longitudinal muscles behind the bolus relax and contract in the front. On a chemical level, when the bolus passes through the intestine, ...
What is released when a bolus passes through the intestine?
On a chemical level, when the bolus passes through the intestine, serotonin (5-hydroxytryptamine) is released by enterochromaffin cells, and sensory neurons are activated. The contraction of circular muscle behind the bolus is due to excitatory transmitters such as acetylcholine, substance P, and neuropeptide Y.
