As food is consumed it is first broken down by enzymes in our saliva
First it enters the mouth then goes down the esophagus ( a long tube made of smooth muscles) I after that, it enters the stomach where it is further broken down by acids. The useful enzymes are sent to the liver to be circulated by the blood vessels. The rest is then sent down to the intestines where the small intestine secretes enzymes ne the large intestine collects waste. The anus and rectum push waste out the body, this waste is known as feaces.
