The most important stage of mechanical digestion is in the stomach, there are muscles in the stomach
wall that churn our food around breaking it into small pieces.
The food when broken down into small pieces in called chyme, this pulverised food provided our
digestive enzymes with much easier access to the nutrients.
What is chemical digestion? - correct answer ✔✔Proteins, carbs and fats are large helical nutrients that
are to big to pass through the wall of our gut into the blood and then be carried by it. They must be
dismantled into smaller molecules. Which usually involves breaking the chemical bonds that hold them
together.
