Digestion is the process of breaking down food into simple form so that it is easily absorbed by the body. Digestion of food takes place in a number of steps. There are several organs of our body, which are involved in this process. They all together make up our digestive system. Digestion of food starts in the mouth. The food is broken down by chewing and grinding into a paste. The paste next moves to the stomach through the food pipe. Food is churned by the stomach muscles with more digestive juices. It is then broken down into simple soluble form. The simpler food now passes to the intestine. Here the food is mixed with more digestive juices and breaks down further. Some of these digestive juices come from the intestine, while other is made in other body organs such as liver and pancreas. These juices complete the digestion of food. The food is now in simple soluble form, which can easily be absorbed into the blood through the walls of the small intestine. The undigested food pass through the large intestine and thrown out of the body through the anus.
