How do you appreciate stomach as a churning machine? How does this coordination go on? (AS6)

a) Stomach acts as a churning machine.

b) When the food enters the mouth, the nerves present in the cheeks and tongue send signals to the brain which stimulates the production of acid and gastric juices in the stomach.

c) This is all coordinated by the autonomous nervous system.

d) The stomach then receisves the olus trough the food pipe by continuous peristaltic movements.

e) The contractions of the stomach squeeze and mix the food with the acid and enzymes of the stomach.

f) The food when properly mixed and grinded, is further pushed on by the peristaltic contractions in the stomach into the duodenum under the action of ANS.
