What are the two organ system involved in providing oxygen to cells and removing carbon dioxide from cells?

The two organ systems involved in providing oxygen to cells and removing carbon dioxide are the respiratory system and the circulatory system. The respiratory system facilitates the exchange of gases in the lungs, where oxygen is inhaled and carbon dioxide is exhaled. The circulatory system, through the bloodstream, transports oxygen from the lungs to the cells and carries carbon dioxide back to the lungs for exhalation. Together, these systems ensure that cells receive the oxygen they need for metabolism while removing waste carbon dioxide.
