Our digestive system consists of a set of organs that take part in breaking down the food to extract the nutrients in it. After extracting the nutrients the wastes are ejected. The first organ that comes in the digestive system is the mouth. It takes in the food and breaks them mechanically. The salivary glands help the mouth in releasing the saliva that helps in breaking the food. Chemical breakdown also takes place since the saliva contains an enzyme amylase. The food reaches the stomach through the esophagus. The gastric juices which could be acidic in nature are secreted in the stomach to further break down the food. After this the food moves through the small intestine where the bile secretion from the liver is added. The pancreatic juice is also added. These are necessary to breakdown the fats taken. At this stage the food is ready for absorption by the blood. Then it moves down to the large intestine and the anus.
