How The Digestive System Works With Other Parts Of The Body ?

No system in the body is isolated. It is always related to other parts or systems of the body. It either aids, or takes the help of other parts for its normal functioning. Similarly, the digestive system works with other parts of the body.

For example, take the rib cage. On the outside it has no relevance to the digestive system.  Yet it serves to protect the esophagus. 

The muscular system also aids the digestive system. The muscles in the jaws help the food to be chewed. The sphincter muscles prevent food from entering the wrong parts of the digestive system. For example, the sphincter muscle at the end of the esophagus prevents food from being pushed up from the stomach into the esophagus. Also, the abdominal muscles serve to hold the rest of the digestive system in place. 

A more complex role is seen with the circulatory system, which absorbs the nutrients from the digested food from the digestive tract via the blood. The circulatory system also aids in the speed of digestion by carrying chemical signals from the endocrine system.

The respiratory system also aids by burping or giving up air so that the extra air that you have taken in via the esophagus and stomach does not hurt the stomach. So, burping is a good thing, though it maybe not good manners!

The digestive system needs the nervous system to perceive changes in the gut, to control secretion of digestive juices and so on. So, it has its own nervous system called the 'enteric nervous system' (ENS).  It works independently of the nervous system.
