The cardiovascular and respiratory systems are largely responsible for the transportation of oxygen and carbon dioxide through the body. Respiration consists of both inspiration and expiration. These actions are the methods by which essential oxygen is exchanged with harmful carbon dioxide. While oxygen is brought into the lungs during inhalation to be processed throughout the body, carbon dioxide is brought during exhalation to be removed from the system entirely. Once the oxygen has reached the lungs it is taken up by the bloodstream in order to be distributed to the various cells that require a constant exchange of nutrients ...
