Practice question

The correct answer is B: Ingestion. In Digestive System, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, this is mainly a definition check, and Ingestion is the standard term or meaning used in Digestive System. That is why Ingestion is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
