What term describes the movement of food from one organ to the next?

• A. Digestion
• B. Secretion
• C. Propulsion
• D. Absorption

Answer: (C)

Propulsion is the movement of food along the digestive tract from one organ to the next, driven by coordinated smooth-muscle contractions known as peristalsis. This forward movement carries swallowed material from the esophagus into the stomach and, as it continues, through the intestines. It’s the process that physically relocates content between organs, distinct from digestion (breaking down food), secretion (release of digestive fluids), and absorption (nutrients entering the bloodstream). While mixing motions like segmentation help with digestion in the intestines, the primary role of propulsion is to push the material onward to the next organ.
