Quote: "One of the jobs of the liver is to inspect the nutrients that are going to go to our bloodstream."

We all understand that the digestive system is simply the process that our body uses to glean the benefits of the foods we eat. Some of us have more knowledge about it than others, and that often comes from the type of education we are exposed to.

For example. students that took biology will perhaps know a lot more than an individual who studied a trade about mechanics. There are many things about the digestive system that are just plain interesting to know. For example...

Did you know that:

In our stomach the food and liquids we take in are mixed with digestive juices. These are all mixed together within the stomach until they are small enough to be absorbed into our system. The interesting part is that each day this all adds up to about 11.5 liters which flows through the digestive system. Out of that entire amount only approx. 100mls is of no value to us, and ends up being passed through the bowels as feces.

The stomach has to break down the different types of food we ingest. One of these being protein. To do the job the stomach secretes enzymes and hydrochloric acid. The stomach is so efficient at its job that between 2-6 hours later it is totally emptied of its contents and is ready for the next batch. Now you know why you're hungry.

Your liver is a food inspector:

One of the jobs of the liver is to inspect the nutrients that are going to go to our bloodstream. Its job is to supply detoxification by getting rid of the impurities. This assists the digestion process. Good reason to keep your liver in top working condition.

That by our not looking after our digestive system properly we could be hurting our financial economy? Well at least indirectly anyways. Digestive problems cost Approx $50 billion every year in America, in both direct costs and individuals suffering from these problems who cannot work.

We may be able to help control indigestion by the way we cook?

In order for us to properly digest our food it takes 100 of enzymes of many different varieties. There are enzymes in our food, but we destroy these when we cook our food. So because the body needs them it is forced to manufacture them. After a while our body may get tired of doing all this extra work, so it will go on strike and not produce a efficient amount. Then once that happens, you better start heading for the antacids, because you are in for a bout of indigestion. With the germs and pesticides and other things that are foods are exposed to, unfortunately we really don't have a choice but to thoroughly cook our foods.

And saving the best for last...

You could stand on your head and the food would still get down to your stomach. Now we really recommend that you don't do this. The reason it will get down there, is because the esophagus is about 25 cm., long, and our muscles will contract in waves to push the food down these 25 cm..

These facts that we have just covered are very interesting to most people. By listening to them or reading them, you have provided yourself with some fairly substantial knowledge about the digestive system. Imagine that, being able to learn something about the human body without becoming overwhelmed or bored. Now that is interesting!
