Rate of digestion increases with increase in surface area


The reason for this is that digestion is the process which is speed up and aided by number of enzymes. And this is one of the people of enzymes that they work more efficiently on larger surfaces. Which means that an enzyme will accelerate a chemical reaction more quickly when provided with greater surface area.
Thus process of digestion is also sped up.

Mechanical digestion of food in which the food gets broken down into smaller chunks, increases the surface area for the action of enzymes and thus facilitate the chemical digestion which involves breaking down the food into simpler nutrients(so that they can be absorbed) by help of enzymes.
