Food is moved through the digestive tract by a sequence of wave-like muscle contractions called peristalsis.

<h3>What is digestive tract?</h3>

The digestive system of the human body is made up of the gastrointestinal tract and additional digestive organs (the tongue, salivary glands, pancreas, liver, and gallbladder).
In order for food to be absorbed and incorporated into the body, it must first be broken down into smaller and smaller components during digestion.
Cephalic, gastric, and intestine phases make up the three stages of the digestive process.
Gastric gland secretions in reaction to the sight and smell of food start the initial stage of digestion, known as the cephalic phase.

<h3>What is peristalsis?</h3>

Peristalsis is the contraction of the muscles. is the contraction and relaxation of radially symmetric muscles that travels anterogradely down a tube in the form of a wave.
In the lining of the gut, a simultaneous contraction of the longitudinal muscle and relaxation of the circular muscle is followed by a coordinated contraction of involuntary circular muscles known as peristalsis.
