Why do heart and lung complications often occur simultaneously?

Heart and lung complications often occur simultaneously because both organs share a common goal of oxygenating the blood. The heart is responsible for pumping blood throughout the body and ensuring that oxygen-rich blood reaches the tissues, while the lungs are responsible for gas exchange, taking in oxygen and expelling carbon dioxide. This interdependence means that any dysfunction in one organ can significantly impact the function of the other. For instance, if the lungs are not effectively exchanging gases due to a respiratory condition, the heart may struggle to pump oxygenated blood effectively, leading to complications associated with both systems. This interconnected relationship highlights the importance of maintaining the health of both the heart and lungs for optimal physiological function.
