wall of stomach is made up of muscles which perform PERISTALSIS

abhisar · Answer

anonymous · Answer

umm I think they used something that started with a b...oh it is bile....they said that has to do with mechanical digestion

anonymous · Answer

in the stomach

abhisar · Answer

no no...bile is produced by liver and is released in small intestine...it is related with chemical digestion

anonymous · Answer

but my teacher said it was mechanical...and when I took a quiz like 3 weeks ago it said the same thing

anonymous · Answer

not that it is made in the stomach but that the stomach uses it to aid in mechanical digestion

abhisar · Answer

no u must be mixing up things

anonymous · Answer

I just pulled up the quiz and looked at it

anonymous · Answer

ok so u were saying something about PERISTALSIS....thats mechanical?

abhisar · Answer

yes Mechanical digestion is the physical division of a mass of food into smaller masses

anonymous · Answer

oh ok...so would separating nutrients from the food and the bad stuff from the food count as mechanical as well?

abhisar · Answer

The mixing action of the stomach walls allows mechanical digestion to occur in the stomach. The smooth muscles of the stomach produce contractions known as mixing waves or Peristalsis (proper medical term)that mix the boluses of food with gastric juice. This mixing leads to the production of the thick liquid known as chyme.

anonymous · Answer

ohhhh That explanation makes sense!....so basically the whole mixing motion is the mechanical digestion?

abhisar · Answer

yes..just converting bigger food particles into smaller by mixing and chewing

abhisar · Answer

chewing occurs in mouth..mixing in stomach
