... ability of haemoglobin carrying oxygen. Therefore effecting transport of oxygen to the respirations sites (during exercise in the muscles). Background information on exercise The reason for my prediction is that more exercise a person does more it will affect the pulse rate of that person. When I mean exercise, I mean more activity a person do, for example running and cycling. The exercise requires movements, so more energy will be required. In order, to get more energy; respiration has to take place at faster rate. As more respiration takes place, more energy is used. Therefore, more carbon dioxide will be produced. Carbon dioxide is a waste product of respiration. So it must be removed from our blood (circulatory system), as it is a toxin. Because of the extra carbon dioxide being produced and blood has higher concentration of carbon dioxide. To get rid of the extra carbon dioxide, blood is pumped around ...
