Food passage order in the digestive tract

Steps:

• Food enters the esophagus (L) after swallowing, moving it first.
• From the esophagus, food reaches the stomach (M) for initial digestion.
• Partially digested food then enters the duodenum (K), the first part of the small intestine.
• After the small intestine, contents pass to the colon (J) in the large intestine for water absorption.

Why D is correct:

• D (L→M→K→J) matches the anatomical sequence: esophagus to stomach to duodenum to colon, as defined by the digestive tract's structure.

Why the others are wrong:

• A starts with duodenum (K), but food doesn't begin there.
• B places colon (J) last correctly but starts with esophagus (L) then jumps to duodenum (K) before stomach (M), skipping the stomach.
• C begins with stomach (M) then reverses to esophagus (L), which is impossible as food flows downward.

Final answer: D
