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.
