the respiratory and circulatory system WORKING TOGETHER
The respiratory system works with the circulatory system to keep your heart beating. Oxygen moves from the alveoli to tiny blood vessels, called capillaries. Once it gets into the bloodstream, oxygen attaches to a molecule called hemoglobin inside the red blood cells. The newly oxygen-rich blood flows back to the heart, which pumps it through the arteries to tissues throughout the body.
Once the blood reaches the capillaries in other body tissues, oxygen is released from the hemoglobin into the cells. Carbon dioxide moves out of the cells, into the capillaries, and back into the bloodstream. The carbon dioxide-rich blood makes it's way back to the lungs, where the gas moves into the alveoli and is exhaled. Then the whole process begins again.

Notice how important oxygen is in this system as well. Without the respiratory system, the circulatory system wouldn't be able to work. Can you name the parts of the respiratory and circulatory systems that overlap?
