Oxygen is essential to keep us alive. Adequate levels of oxygen is very important to cell respiration.

The heart and lungs have a relationship that makes sure that there is sufficient supply of oxygen in the blood.

The heart sends deoxygenated blood to the lungs. The blood that goes through the lungs are given oxygen. The blood becomes deoxygenated again, and it is sent back to the lungs, and the cycle goes through.

This is the interaction between the heart and the lungs.
