The circulatory system is responsible in distributing oxygen,nutrients in the body.
The repiratory system gets the oxygen then exchange of gases occur in the alveoli (oxygen-carbon dioxide) the oxygen enters the circulatory system through the capillaries in the alveoli then the blood carries the oxygen to the heart to be pumped throughout the body.
