The digestive‚ respiratory and the cardiovascular system are all interrelated in order to make the human body work effectively and efficiently by working as an orchestra. The cardiovascular system and the respiratory will work together in order to perform the gas exchange which is passing of oxygen from the alveoli into the blood flow and then the carbon dioxide passes trough the blood flow and is breathed out from the body. This means oxygen (in) CO2 (out).
