Contraction action is taking place during digesting lunch

Explanation:

During lunch is taken, Food is chew and turned down to a form known as bolus. This bolus is sent to food pipe via esophagus.When the bolus reaches esophagus due to contracting and relaxation of smooth muscle in alimentary canal bolus is pushed towards the stomach along with nutrients.The repeating contraction and relaxation process is known as Peristaltic action. This causes food to reach stomach.
