Tracing a Meal Through the Digestive Tract, Worked
Captions available
The idea
This capstone traces one meal's complete path from ingestion through the digestive tract to nutrient absorption, drawing together this chapter's mechanical, chemical, and organ-level atoms.
Where people slip
Assuming one enzyme handles a whole meal at once is the error here — three separate digestive pathways run in parallel through the same tract, each with its own enzymes, timing, and site of completion.
