Digestion is the breakdown of food substances by enzymes to simpler compounds that can be absorbed. Digestion begins in the mouth. Once food is ingested in the mouth, it is chewed and broken into small particles suitable for swallowing. Mechanical procesing of food is through the wave-like contractions of the muscular walls of the alimentary canal called peristalsis. Churn and pound food mixing it with digestive enzymes.
After digestion, absorption and assimilation, the final product is oxidized to provide energy to the body.
