Peristalsisis a radially symmetrical contraction and relaxation of muscles which propagates in a wave down the muscular tube, in an anterograde fashion. In humans, peristalsis is found in the contraction of smooth muscles to propel contents through the digestive tract. Earthworms use a similar mechanism to drive their locomotion.[1] The word is derived from New Latin and comes from the Greek peristallein, "to wrap around," from peri-, "around" +stallein, "to place".

Anal-administration of substances works because of this fact.
Wave-like contractions of the smooth muscle called peristalsis moves food through the digestive system.The muscles in the lining of these organs contract and relax from above the food which pushes the food downwards. this process works even if you stand upside down. it can face the strongest force of gravity very easily.The digestive system helps the body digest food. Bacteria in the GI tract, also called gut flora or microbiome.
the digestive system works with our other system in different ways. one example is the liver. the liver sends out nutrients to through out the body and after the small intestines absorbs the nutrients and give the to the liver. the liver need to help the circulatory system to do it. the blood vessels of the liver gives the nutrients back to the body, and that's a example of how the digestive system works with other systems in your body.
