first the food stars in the mouth where it is chewed. Then it gets pushed by the tongue in to the esophagus where peristalsis ( wavy muscle contraction) push the food in to the stomach. Here acids and gastric juices breaks down and kills bacteria and churned for about 4 hours before being pushed in to the small intestine. Here is where most of the digestion occurs. The small intestine is the longest path way or tube in the digestive system. After that it gets pushed in to the Large intestine where water is such out of what is left and travels through to the rectum where is stored and then defecated ( or pooed) out through the anus.

The food comes to your mouth and by chewing it mixes with saliva. This one starts the digestion due to tialine, one substance that brokes the food and transforms it in a mass named bolus. The bolus passes through the esophagus to the stomach thanks to peristalsis, and suffers another undo with acids and gastric juices. The product moves toward the small intestine and here continues the digestion when the product is absorbed by the micro villi, microscopic elongations in the internal wall of the tube. The micro villi have many blood vessels named capilars, that absorb the nutrients and transport them to the blood stream, and eventually carry them to all the tissues of the body in the blood cells. These ones take the excretions out of the tissues and eliminate them to the small intestine, in which forms a solid mass, that loses water as it passes to the large intestine, due to the recover of water in the micro villi. In the large intestine the mass stores and eventually is thrown out of the body by defecation.

first of all food enters into buccal cavity through mouth, here it mixes with saliva and masticated with the help of teeth.tongue helps in swallowing of food. From oral cavity it enters into the oesophagus, then into stomach, from stomach food enters into small intestine, from small intestine food enters into large intestine.in stomach digestion of proteins takes place with the help of enzymes ( renin and pepsin). in small intenstine sugars digestion takes place with the help of sucrases, maltases and lactases. Bile juice which is stored in the gall bladder helps in emulsification of fats.
