The digestive acids in your stomach are strong enough to dissolve zinc. Since the cells in the stomach lining are replaced rapidly, with about five hundred thousand cells being replaced every minute, and the entire lining every three days, the acids do not have time to dissolve the lining. Now, that’s quite a save!
It is difficult (and sounds odd), but it is possible to eat when you are upside down! The digestion process defies the laws of gravity!
Contrary to their names, the small intestine is 22 feet long while the large intestine is just 6 feet long.

The liver is the centre of our metabolism, a complex chemical factory and filter that controls the body’s absorption of food. It carries out more than 500 separate processes concerned with regulating all the main chemicals in blood and many other life-supporting functions.
The cells along the inner wall of our stomach secrete about 2 litres of hydrochloric acid every day!
Every day our salivary glands produce between 1 to 2 litres of saliva.
It takes approx 7 seconds for the food you eat to travel down to your oesophagus.
