15 Respiratory and Circulatory Systems work together? __

Yes, the respiratory and circulatory systems work together to deliver oxygen to the body's cells and remove carbon dioxide. The respiratory system is responsible for taking in oxygen and expelling carbon dioxide. The oxygen-rich air is then passed into the blood in the lungs. The circulatory system, specifically the blood vessels and the heart, then transport this oxygen-rich blood to the cells throughout the body. At the same time, the circulatory system carries carbon dioxide, a waste product of cellular respiration, back to the lungs where it is expelled from the body.
