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.
Through respiratory system, the oxygen enters the body and then it is transported as oxyhaemoglobin to the cells with the help of cardiovascular system. The cardiovascular system also performs the work to transport the waste product carbon dioxide to respiratory system, that evacuates it.igestive system breaks down large molecules (e.g starch) into simple molecules such as glucose. These are then transported to cells of the body via the circulatory system. The respiratory system causes the diffusion of oxygen into the blood and the diffusion of CO2 out of the blood.
