Even though the systems may seem very separate in their activities the digestive system and respiratory system both contribute to work together. The systems cannot work by themselves as they both provide the materials needed throughout the body. They supply energy to all the cells throughout the body. The respiratory system and digestive system allow each other to function.

The digestive system is made up of all different organs which starts at the mouth and finishes at the anus but on the way involves all other organs; these organs help to break down and absorb the food.

The digestive system is dependent on the respiratory system as it needs the respiratory system for it to work correctly. The digestive tract which includes the mouth, pharynx, oesophagus, stomach etc. uses muscles to make it contract so that the food can be broken up and also to move the food along the tract. Some of the muscles in the stomach turn the food into a liquid and then muscle contractions from the small intestine move it through the rest of the system. In order for these muscles to work in the way they do they need oxygen, therefore without the respiratory system the muscles would not be able to work. Also the respiratory system removes all carbon dioxide and water that the cells produce as a waste product.

The respiratory system’s main function is to supply the blood with the oxygen it needs to transport around the body to all of the different organs. The way in which the system does this is by breathing; this is an involuntary action of the body. This system/ process are done by using the mouth, nose, trachea, lungs, diaphragm and the bronchi. It starts by our bodies inhaling oxygen, the oxygen then goes onto the larynx and then through the trachea into the chest cavity. The trachea then branches off into two smaller tubes which are called the bronchi. These tubes then split into even smaller tubes names bronchial. These tubes then go directly into the
