| Food provides us with fuel to live, energy to work and play, and
the raw materials to build new cells. All the different varieties of food we
eat are broken down by our digestive system and transported to every part of
our body by our circulatory system. |
| |
| Our digestive system is a 9 meter long tube. The digestive
process begins in the mouth, where the teeth and tongue break up the food
after it has been softened with saliva. The food is then swallowed and
travels down the esophagus to the stomach. |

| While the food is in the stomach, it is mixed with a mild acid
which breaks the food down into a paste similar to porridge. The food then
passes, a little at a time, into the small intestine, which is roughly 6
meters long. Here the food is broken down even further until it is small
enough to pass through the walls of the small intestine into the bloodstream.
Food that cannot be digested passes into the large intestine, where the water
and minerals are absorbed into the blood stream. The solid waste, the feces,
is then expelled from the body through the rectum and anus. |
