What is the relationship between the heart and the lungs can be described as?

The relationship between the heart and the lungs is a vital component of the circulatory and respiratory systems. The heart pumps deoxygenated blood to the lungs through the pulmonary arteries, where carbon dioxide is exchanged for oxygen. The oxygenated blood then returns to the heart via the pulmonary veins, allowing the heart to distribute oxygen-rich blood throughout the body. This collaboration ensures that tissues receive the necessary oxygen for metabolism while removing carbon dioxide efficiently.
