Name two regions of the digestive tract where mechanical food breakdown processes are very important. Name two organs that are primarily food conduits. Name the organ where protein digestion is begun. Name the organ where fat digestion begins
What will be an ideal response
Mechanical food processes are very important in the mouth (mastication) and stomach (contractions causing mixing of food into chyme). The esophagus and pharynx are primarily food conduits. Protein digestion begins in the stomach. Fat digestion begins in the small intestine.
