They are bordered by the rib cage, protected by the sternum in front and the spine behind, and separated by the mediastinum, which houses the heart and major blood vessels. Functional Differences Beyond Size While the right lung is bigger, the difference in function between the two organs is minimal.
How Available Space Shapes Lung Size and Form
The space available dictates the ultimate size and shape of each lung. This three-lobed structure allows for a greater surface area, facilitating a higher volume of gas exchange with the blood that flows through the pulmonary capillaries.
This size difference is necessary to fill the extra space in the chest cavity. To make room for the heart, the left lung is narrower and features a distinct indentation known as the cardiac notch, which allows the organ to fit snugly in the available space.
