Here's a breakdown:

* Digestion is the breakdown of food into smaller molecules that the body can absorb and use for energy, growth, and repair.

* This process involves both mechanical (physical breakdown, like chewing) and chemical (using enzymes to break down complex molecules) processes.

* It starts in the mouth and continues through the stomach, small intestine, and large intestine.

* The small intestine is the primary site of nutrient absorption.

So, while digestion is the overall process, the specific part that makes food absorbable is the breakdown of food into smaller molecules, which happens throughout the digestive tract.
