The two systems are known as the cardiopulmonary system. One system cannot function properly without the perfect function of the other. Such as with people with COPD, chronic obstructive Pulmonary diseases. The respiratory system is damaged affecting oxygenation. Without, proper lung function the heart has to work harder and in time causing the heart to grow larger and weaker, this is called cardiomegaly.
One system is dependent on the other. The cardiopulmonary system is best monitored by a pulmonologist when compromised .
