Question

stomach: the food is churned: ?

Answer 1

Here, peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion). ... Food is digested in the stomach for several hours. During this time, a stomach enzyme called pepsin breaks down most of the protein in the food.

Answer 2

The food is churned in mouth.
And in the stomach bolus is material which is formed....and then enters to rectum
Hope this works ??????
