Question

What is peristalsis?

Answer 1

Peristalsis:

1. The semi-digested food in the mouth will become a soft ball-like form called bolus.
2. This bolus swallows and reaches the stomach through a pipe called esophagus.
3. The contraction of muscles present in the esophageal wall produces a wave-like motion which facilitates the movement of bolus through the esophagus. This wave-like movement is called peristalsis.
