Question

how does food passes through alimentary canal?

Answer 1

Answer:

Its job is to move the bolus into the stomach. Food is moved through the esophagus (and other parts of the alimentary canal) by a wavelike muscular motion known as peristalsis (pronounced pear-i-STALL-sis). This motion consists of the alternate contraction and relaxation of the smooth muscles lining the tract.
