In order to use the food we eat as energy , our body has to break the food down into smaller molecules that it can process; it also has to excrete or get rid of waste. Most of the digestive organs like the stomach and intestines are tube-like and contain the food as it makes its way through the body.

The digestive system is essentially a long, twisting tube that runs from the mouth to the anus, plus a few other organs like the liver and pancreas that produce or store digestive chemicals. Without the digestive system, our bodies would not be able to get nutrients from the food we eat or get rid of the waste products that food makes and we would soon become ill!

Our body needs food to provide it with energy, vitamins, and minerals. However, in order to use food, we must first break it down into substances that the various organs and cells in our body can use. This is the job of our digestive system. The digestive system acts in stages to digest our food. Each stage is important and prepares the food for the next stage. The entire length of our digestive system is around 20 to 30 feet!

Chewing is the very first stage of the digestive system. When you chew your food it breaks up big pieces into little pieces that are easier to digest and swallow. Also, your saliva is more than just water. It has special enzymes in it that start to break down starchy food potatoes, bread while you chew. Swallowing is the next step in the process. You might think it happens all by itself, but food doesn't just fall down our throats into our stomach.

Firstly, our tongue helps to push the food into the back of our throat. Then there are special throat muscles that force the food down into a long tube that leads to our stomach, called the oesophagus. The food doesn't just fall down the pipe, muscles push the food along until it gets to our stomach. At the same time all this is going on, a flap blocks off our windpipe making sure food doesn't go the wrong way. We call this "going down the wrong pipe" and it can make us choke.

This flap is called the epiglottis and, fortunately for us, it works automatically. The next stage is the stomach. Food stays in the stomach for about four hours. While the food sits there, more enzymes go to work on it, breaking down things like proteins that our bodies can use. The stomach kills a lot of bad bacteria as well, so we don't get sick. The next step in the process is the small intestine. The first part of the small intestine works with juices from the liver and pancreas to continue to break down our food.

The second part is where the food gets absorbed from the intestine and into our body through the blood. The last stage is the large intestine. Any food that the body doesn't need or can't use is sent to the large intestine and later leaves the body as waste.

The liver and pancreas do a lot to help the digestive system along. Both work with the small intestine. The liver provides a substance called bile and this is stored in the gall bladder.

Bile helps break up fat into smaller parts. The pancreas provides more enzymes to help digest all sorts of food. The liver also processes all the digested food from your blood before it gets sent to hundreds of places in your body to be used. All these points noted down with Digestion assignment help is to be kept in mind to live a healthy life.
