Final answer:

Peristalsis is the key process that moves food through the gastrointestinal tract efficiently.


Explanation:

Peristalsis is the process that moves food through the gastrointestinal tract. It involves sequential waves of muscle contractions and relaxations that propel food in one direction, from the esophagus to the anus.

Peristalsis is a vital part of the propulsion process in the digestive system, ensuring that food moves efficiently through the alimentary canal. This movement helps with mixing food with digestive juices and breaking down food into smaller pieces.

The digestive system consists of various organs working together to carry out digestion, absorption, and elimination processes, ultimately extracting nutrients from food and expelling waste.
