The answer is : ingestion and digestion ; propulsion and secretion ; absorption and elimination

Digestive system will receive and digest food to make the molecule smaller. After the molecule become small, it could be absorbed by the body. The waste that couldn't be digested and absorbed will be eliminated as feces. Some of the waste from the body like bilirubin would be dumped through feces too.
