Practice question
Question
Mechanical digestion refers to:
Explanation
Pick C: Physical breakdown of food. Thinking about Digestive System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: this is mainly a definition check, and Physical breakdown of food is the standard term or meaning used in Digestive System. Hence Physical breakdown of food is correct. Treat this as a building block for the rest of Digestive System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.
