Functions of the Digestive Organs

For the proper functioning of the body and for giving it the required energy we need food. Food is first chewed by the teeth in the mouth where saliva gets mixed with it. This saliva is a digestive juice and helps in the digestion of food. It also softens and moistens the food so that it can easily go down our throat into the food canal which is connected to our stomach. In the canal it gets mixed with another juice. The food then passes into the stomach where it undergoes many chemical changes. In the stomach, the food is churned the same way as the curd is churned for making butter.
The stomach is connected to the small intestine. At the Joint of these two is a covering or valve. When food is churned completely this valve opens automatically and the food is transferred to the small intestine. This process goes on in the stomach for three to five hours. If the food is light the stomach soon becomes empty. But if the food is heavy or full of chilies and spices or fried, it takes longer time to be digested. In the intestines it gets mixed with several other juices which help in its digestion. The small intestine takes out the digested food elements and absorbs them in its walls it then pushes the food through the motion of contraction and expansion. The small intestine is about 7 meters long. The food juices absorbed by the intestines go to the liver and the waste material passes through the length of the small intestine and goes over the large intestine. This process goes on in the small intestine for five to seven hours.

The small intestine absorbs almost the entire food juice. Whatever is left is taken by the large intestine and the waste product is passed on to the exterior, called the rectum. This process also takes about six to seven hours. This way, our body takes about 14 to 18 hours to completely digest a food item.

The food juice extracted from the food by this process then goes to liver, which makes blood from it and sends the blood to the heart. The other dirty liquid is sent to the kidneys. The kidneys purify it and send the uric acid to the bladder, from where it comes out in the form of urine.

In this way nature has made our body a well-organized unit without leaving any flaw in it. It is not that the foot is pricked with a thorn and the hands do not try to take it out or the eyes refuse to find the exact place of the prick. When the foot gets a thorn, the other parts help it to remove it. External attacks on our body are faced by the organs collectively: the brain thinks and commands, the eyes see, the hands exert their force and take the thorn out. In the same way, if the body is attacked by a disease, all the concerned organs try their best to throw it out and to free the body from it. If we do not prevent the organs to do so by our wrong food or by taking medicines, the organs do their best to throw out the disease. Yogasanas are very essential for the proper functioning of our organs, mid for the accumulation of protective energy in the organs, so that the body continues to function in normal and healthy way.
