YOUR AMAZING BODY

THE acid in your stomach is so strong you could use it to make your own toilet cleaner.

Cells along the inner wall of the stomach produce gastric juices – up to two litres – that include highly corrosive hydrochloric acid to kill bacteria, prevent infection and aid digestion.

The same chemical is used to make potent products that remove rust and limescale from toilet bowls and some kitchen cleaning products that tackle stubborn stains.

To prevent the acid burning through the stomach lining, the cells also produce a new protective coating of mucus every two weeks.
