Practice question

Correct option is B, Bolus. In Digestive System, the accurate description is Bolus, and that is what you should commit to memory. Keep the definition tight and the role clear — this is mainly a definition check, and Bolus is the standard term or meaning used in Digestive System. Then Bolus is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Bolus. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
