Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body's cells. Every three to five seconds, nerve impulses stimulate the breathing process, or ventilation, which moves air through a series of passages into and out of the lungs.
In the circulatory system, when the body aquires oxygen diffusion takes place. In the capillaries, oxygen diffuses into the bloodstream, while carbon dioxide diffuses out.Without diffusion could not aquire for oxygen to got to the heart and circulate through out the body.his occurs in the lungs and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel in the form of ATP (adenosine triphosphate) for energy, thus creating more carbon dioxide.
