Digestion begins in the mouth, when you eat and swallow, and is completed in the small intestine. The act of swallowing sends food down the esophagus or throat into the stomach. Then like a food mixer, the stomach contracts to break this nourishment down with the help of acid and enzymes.These nutrients, which are now liquid, then travel into the small intestine, which can be over six metres long. It is here that most nutrients are transferred into the blood stream .Waste products from the entire progress are then sent out of the body through the large intestine.

Digestion begins in the mouth when youn swallow and eat,breaking the food into molecules.First,the act of swallowing send the food down the esophagus,or throat,into the stomach.Then,the stomach contracts to break this nourishment down,helped by acid and enzymes.These nutrients then travel into the small intestine which can be over six meters long.It is here that most nutrients are transferred into the blood stream.Waste products are then sent out of body through the large intestine.

digestive system can turn the meals we eat into the energy which are used by our bodies. First ,we put the food into our mouth. And the act of swallowing sends food down the esophagus or throat into the stomach. Then, the stomach contracts to break this nourishment down helped by acid and enzymes .After that, these nutrients, which are now liquid ,travel into the small intestine, where most of them are transferred into the blood stream.

Food through oral chewing, grinding teeth, tongue stirring, swallowing, gastrointestinal muscle activities, will be large pieces of food into small pieces, so that the digestive juice fully mixed with food, and promote the food ball or chyme down, from the mouth to the anus, this kind of digestion process is called mechanical digestion, or physical digestion.

The function of the digestive system is to transform the food we eat into the energy used by our bodies.First, we put food in our mouths.And swallowing sends food to the oesophagus or the throat to the stomach.Then the stomach compress to break this power down with acid and enzymes.These nutrients, which are currently liquid, then enter the small intestine, where most of them are transferred to the bloodstream.

The main work of the digestive system is to transform the food we eat into the nutrients our body needs.After we chew food with our teeth,it goes into the esophagus or into the stomach through the throat.The stomach then breaks it down into nutrients with the help of various enzymes and acids.After that,the nutrients become liquid,some into the blood stream.

Through oral chewing, tooth grinding, tongue stirring and swallowing, and gastrointestinal muscle activities, the food turns large pieces of food into small pieces, so that the digestive juice is fully mixed with the food, and the food ball or chyme is pushed down from the oral cavity to the anus.

Digestive system starts from our mouth. The action of swallowing when you are eating sends food down the esphagus and throat, and then into the stomach. After that, with the help of acid and enzymes, our stomach contracts to break nourishment down, making the food smaller pieces for easily digesting. Once the nourishment are broken down into nutrients, they can travel into our small intestine as they were transformed into liquid. Small intestive is more than six meters long, absorbing most of these nutrients and send them to bloodstream. Finally, waste products will be send out through our large intestine. That is how Digestive System works.
