It is the smooth muscle contractions that move food through the esophagus and intestines.

It's the rate at which digested/undigested food passes through the bowel. I have a very slow peristalsis. This means that when I eat a really HOT meal, it's at least a day before I feel the heat when defecating. Nothing to do with constipation.

Peristalsis is the rhythmic contraction of smooth muscles to propel contents through the digestive tract.
In much of the gastrointestinal tract, smooth muscles contract in sequence to produce a peristaltic wave which forces a ball of food along the gastrointestinal tract.
Peristaltic movement is initiated by circular smooth muscles contracting behind the chewed material to prevent it from moving back into the mouth, followed by a contraction of longitudinal smooth muscles which pushes the digested food forward.

Peristalsis is the rhythmic contraction of smooth muscles to propel contents through the digestive tract. Circular smooth muscle contract behind the food to keep it from coming back up while longitudinal muscle muscles contract to propel it along the GI tract.

The process of successive wave like contractions of the muscular walls of the intestines, forcing food through the system.

Peristalsis.
This is the action of the intestines that moves food through them - kind of like a gentle undulating. It's actually the same principle as how a snake moves along the ground!

i think it is the motion inside the digestive system that gently moves the food along
the food does not simply fall into our stomach , peristalsis also means we could eat our food sitting on our heads
ie it is not gravity but perestalsis that ensures the food is gently carried to the stomach

peristalsis is the wave like contractions in the food pipe when u swallow ur food.
these waves actually squeeze the food and push the food into the stomach from the wind pipe.

peristalsis i a wave like motion that occurs in the intestines or organs it is induced by distension of the circular muscles in the intestines

It's the involuntary waves of muscle contraction that push your food through your body.
