System Responses


When exercising the working muscles need to have greater amounts of oxygen and energy delivered by the cardiovascular system. This needs to happen to meet the increasing needs during activity. The working muscles need to have more blood, this speeds up the removal of carbon dioxide and other wastes. In order to do this the cardiovascular system undergoes a number of changes.
