DIGESTIVE SYSTEM.
We eat food to remain alive. Food gives us energy. But the food has to be broken down into simpler substances so that it can be absorbed by our body. This process
is called digestion.Digestion
The process in which complex food is broken down into simple, soluble substances so that it can be absorbed easily, is known as digestion.
Mouth
Food is taken into our mouth. Teeth present in the mouth chew and grind the food. When we chew, the food gets mixed with saliva. Saliva helps in the digestion of
starch and converts it into soluble sugar. It is secreted by three pairs of glands called salivary glands. They are located in the bottom and sides of mouth.
Food pipe
Food pipe is also known as oesophagus. In a grown up person, it is eight to ten inches long. Food passes through this long tube to reach the stomach.
Stomach
The stomach is a hollow, muscular bag. The walls of the stomach secrete digestive juices called gastric juices. The juices in the stomach breakdown the proteins in the food.
Small Intestine
From the stomach, the food is pushed into a long coiled tube called the small intestine. Three juices; intestinal juice, bile juice and pancreatic juice are poured into the small intestine. These juices help to complete the process of digestion. The digested food is absorbed by blood vessels which carry nutrients to all parts of the body.
Large Intestine
The undigested food passes into the large intestine. Extra water is absorbed from the undigested food and carried to kidneys by blood vessels.
Anus
It is the opening, through which solid waste is thrown out of the body.
