Digestion is a very important process for the proper functioning of our body. Through the process of digestion the nutrients and water is absorbed from the food and used up in the body which gives energy to the body to perform work. Even the working of organs in our body needs energy.The process through which the food enters our body and is then passed through various organs in order to get digested is governed by the digestive system. It comprises of various glands and organs such as salivary glands, mouth, esophagus, stomach, liver, gallbladder, pancreas, small intestine, large intestine, rectum and anus.
Initially food enters our body from the mouth, the fluid secreted by the salivary gland moistens the food and the teeth churns it. The churned food with the saliva then goes into the food pipe called the esophagu sand through food pipe it reaches the stomach. In stomach it stays for 5-6 hours where the food is mixed and grinded and with the help of certain enzymes and acids the food breaks down and becomes of a paste consistency.
Then the food enters the small intestine where the process of breaking down of food continues with the help of the secreation of pancreas that is pancreatic juice and liver is bile. Here, the nutrients and broken down into its simplest form such as proteins are broken into amino acids, fats into fatty acids and then are absorbed.
Then the semi liquid paste enters the large intestine where the water and electrolytes are absorbed from the digested food.
Then the left over waste collected in the rectum and excreted through the anus and is eliminated out.
For the process of digestion to take place smoothly as it helps the smoothen the movement of food in the system and cleanses the digestive system. By taking the right amout of water constipation does not takes place.
