The Circulatory System Review The circulatory system facilitates the transportation and exchange of oxygen, carbon dioxide, and nutrients. Blood Red blood cells: Carry oxygen to cell and carbon dioxide away from cells White blood cells: Play a role in fighting infection and protecting the body against pathogens Platelets: Help the body form clots to repair damage done to the blood vessels.
