Circulatory system is an organ system that transports blood carring oxygen,nutrients molecules such us glucose and other raw materials to the cells of the body.Breathing system supplies oxygen for the and also removes carbon dioxide. In order to carry out all the live process cells need energy. T his energy is provided by a process called respiration.
The air you breathing is different from the air you breather out you, removes oxygen from the air N add carbon dioxide and water to it.
All cells and tissues need a good blood supply to provide glucose and oxygen for respiration and to carry away carbon dioxide.If exercises very hard your lungs N blood cannot keep up the supply N your muscles cells run shot of oxygen.
