Most of the digestive tract, from the lower esophagus, the stomach, the small and the large intestine, is lined with smooth muscle. It is organized in two directions: linearly, along the length of the tube, and circularly, around the circumference of the tube. In different sections of the tube, there are alternate contractions of the circular muscle (which squeezes it together, and tends to push the contents along), and contacttions of the longitudinal muscle, which tends to stretch the tube out. These alternating waves of contraction are called peristalsis.

well food is put into the mouth and then the salivary gland secretes saliva which
mixes in the food. It moves down through the throat and into the esophagus then into the stomach where the food is churn and digested, and is mixed with all type of things such as chyme and gastic juices, food then travels to the small intestine where intestinal juice is secreted, Cabs and proteins get digested here, final digestion also occurs here. food is made ready as waste in the large intestine then traveled into the anus then to the rectum where it leaves the body.
this is just a general overview hope it helps

By muscle contractions that are similar to squeezing a tube of toothpaste from the end. These muscle contractions come in waves and are known as peristalsis.
