Digestion in terms of a conveyor belt sushi restaurant
Digestion is essentially a Yo Sushi conveyor belt where the chef is blindfolded and the customers are armed with industrial-grade hydrochloric acid.
The process begins at the entrance with a mastication booth, where your teeth act as a very aggressive sous-chef, hacking your prawn katsu curry into a manageable paste. Once this glob hits the stomach, the staff douse it in acid, turning the conveyor belt into a churning mosh pit of chemical reactions. It is a frantic, chaotic scramble to break the sushi down into tiny nutrient plates, ensuring that by the time it reaches the small intestine, everything is small enough to be pinched by the waiting blood-vessels-as-waiters.
Those small intestine waiters are surprisingly efficient, snatching up every molecule of protein or fat the moment it drifts past their station. By the time the remains reach the large intestine, the posh sushi experience has been downgraded to a sad, leftover buffet consisting entirely of damp fibre and shame. The staff here simply mop up the remaining water, leaving you with a final, compressed parcel that is ready to be evicted from the premises entirely. You pay the bill, leave a tip for the microbiome, and wonder why you spent twenty quid on something that will inevitably exit via the rear staff door within twenty-four hours.
Where the analogy breaks downThe stomach does not actually employ a blindfolded chef to hurl acid at your lunch.
