FACTS · 拆解流水線 The Disassembly Line
The film is a style demo, not a physiology lesson: each organ is drawn as one machine, and the voice says one thing per station. This sheet lists what each station and line claims, where it comes from, and where the metaphor simplifies. Sources fetched 2026-11-04.
Stations
| Station on screen | What the picture and voice say | What the sources say | Source |
|---|---|---|---|
| ① CRUSHER · 口腔 | teeth crush the sandwich, a saliva spray falls | teeth break food down; salivary amylase starts breaking down starch in the mouth | NIDDK |
| ② ACID DRUM · 胃 | "An acid drum churns it all to paste" | the stomach mixes food with acid and enzymes into a semi-liquid (chyme) | NIDDK |
| ③ GATEKEEPER · 幽門 | "lets it out, a spoonful at a time" | the pyloric sphincter lets chyme into the duodenum in small portions; "a spoonful" is a figure of speech | Britannica, "human digestive system" |
| ④ SORTING LINE · 小腸 | "bread into sugar, ham into amino acids, cheese into fatty acids" | carbohydrates → simple sugars, proteins → amino acids, fats → fatty acids and glycerol | NIDDK; Britannica |
| pipes to the liver | the ochre (sugar) and vermilion (amino acid) pipes go up into the liver; the teal (fat) pipe turns away | sugars and amino acids reach the liver through the portal vein; fats enter the lacteals and the lymph first | Britannica, "human digestive system" |
| ⑤ WAREHOUSE · 肝 | "The liver shelves the sugar, and it waits"; the warehouse sits above the stomach floor, under the diaphragm | the liver stores glucose as glycogen and releases it between meals; it lies in the upper right abdomen under the diaphragm | Britannica, "glycogen"; Britannica, "liver" |
| clock 12:30 → 1:15 PM → 6:30 PM | "6 hours later: the bus" | food passes through the stomach and small intestine in about 6 hours on average (6–8 hours on the second page); after a meal blood sugar starts rising within 15–30 minutes and peaks after about an hour, so 1:15 PM is "shelving has started", not "done" | Mayo Clinic; Mayo Clinic Care Network; general physiology (no single source) |
| ⑥ FURNACES · 肌肉 | "Down the arteries, into tiny furnaces" in the thigh | mitochondria in muscle cells use glucose and oxygen to make ATP; "furnace" is a figure of speech | Britannica, "mitochondrion" |
Simplifications
- Bread = sugar, ham = amino acids, cheese = fatty acids. The film gives each food one nutrient so that the three colours can be followed. In reality bread also contains protein, cheese is rich in protein as well as fat, and ham contains fat. The voice says "bread into sugar, ham into amino acids, cheese into fatty acids" as shorthand for "mostly".
- Running on the liver's sugar. The film sends the sugar the liver stored down the arteries to the leg's furnaces. When running, muscles draw mainly on their own glycogen; liver glycogen mainly keeps blood sugar steady, which the muscles also use. The film shows only the liver's part.
- One pipe per nutrient. The three coloured pipes stand for blood and lymph routes; there is no single "sugar pipe".

Invented for the film
The sandwich, the 12:30 lunch ticket, the clock times, the bus (route 6) and the stop, the factory, its workers and every machine are fictional. No real company, product or logo appears.
