Mechanical digestion, the process of breaking down large chunks of food into smaller pieces, is important because smaller pieces of food mechanical digestion, the process of breaking down large chunks of food into smaller pieces, is important because smaller pieces of food do not taste as good as larger pieces of food are easier to excrete than are larger pieces of food are more easily stored in the stomach than are larger pieces of food have more surface area for chemical digestion than do larger pieces of food

have more surface area for chemical digestion than do larger pieces of food.

Explanation:

Human body cannot digest food directly and therefore there is a complex system of digestion which changed the food we eat into more simple elements that could be used by cell to deliver it to the rest of the body. Mechanical digestion starts in the mouth where a large chunk of food is broken down into small pieces so that these small food particles are mixed with saliva and biochemical reaction reduced it into a more simple form. The smaller the food particles the better area would be provided for the chemicals to act on them.
