The digestive system starts here at your mouth which contains teeth, saliva, and a tongue. The mouth breaks down the food you put in it such as cookie.

Next is the esophagus. It will contract that cookie you ate and send it to your stomach. The esophagus Is a hollow muscular tube.

The stomach is a hollow muscular pouch. It Uses muscles, acids and other chemicals to break down that Cookie into smaller pieces.

Next your cookie goes threw the small intestines. It is a tube lined with villi. It will Absorb nutrients from the cookie into the blood and chemically digests the cookie.

Now comes the Liver which is a large, heavy, triangular shaped organ and Aids in digestion by producing chemicals that break down your cookie you ate.

The next cycle of digestion is the large intestines. It's a Tube that contracts and pushes waste toward the anus. It also absorbs water back into the blood.

Lastly is the anus. It is a muscular opening the allows waste, like the leftover of your cookie, to exit the body.
