Answer 2

$\huge\mathfrak\red{Answer:}$

From the mouth, the food is pushed down into the next organ called the food pipe oesophagus. It acts as a passage to carry the food from the mouth to the stomach. No digestion of food takes place in the oesophagus. The food is pushed down in a wave- like motion caused by the contraction and relaxation of the oesophagal muscles. This wavy movement is called peristalsis, which is observed throughout the alimentary canal.
