the rippling motion of muscles in the digestive tract in the stomch this motion mixes food with gastric juices turning it into a thin liquid

Answer 2

hey buddy,

the rhythmic movement of food in the gut ( alimentary canal ) is called peristalsis. it helps in movement of food through the whole alimentary canal.

rumination is a process in which cud of food is partially digested in stomach and then taken back to the mouth for chewing (helps in digesting or breaking cellulose).
