Did You Know?
The left lung is smaller than the right, because it share space with the heart
Your left lung it’s a hero, it sacrifices space so that your heart can be somewhere in your body. That space is called the “cardiac notch” which makes the left lung smaller than the right lung.
The cardiac notch is the lateral deflection of the anterior border of the left lung. It is produced to accommodate the space taken up by the heart.
That is also not the only difference, it also has two lobes compare to three lobes. Together, the lungs contain approximately 2,400 kilometres (1,500 mi) of airways.
