Difference Between Right And Left Lung

Breathing is a natural phenomenon, and the process is carried out by the respiratory system. The lungs are the primary organs of the respiratory system. The lung is divided into right lung and left lung. The right lung is wide and short whereas the left lung is narrow and long. The right lung has a cardiac impression, and the left lung is very close to the heart. The common function of the lungs during respiration is to inhale oxygen and exhale carbon dioxide. Below we have discussed the difference between right and left lung.
