Describe how food travels through the digestive system.

Hi,
The food is chewed and grinned up from the teeth and broken down from saliva, then the epiglottis shuts covering the trachea allowing food to travel
down the esophagus, once it travels down it reaches the stomach which is mechanically and chemically broken down from the stomach muscles and the hydrochloric acid. Then it goes into small intestine, then the large intestine where it is determined to be a solid, liquid, or gas and the liquid is normally drained out causing it to be solid, Then it is eventually stored in the rectum and released through the anus. There are three helping organs the liver, gallbladder, and pancreas which produce the digestive enzymes but arent part of the digestive tract,

The food goes down your throat to the stomach which the acid melts it down to energy which is traveled through you intestines, then out your private parts.. 

Hope it helps :)
