Right Lung vs. Left Lung: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 11, 2023
The right lung, with three lobes, is larger but shorter due to liver displacement, while the left lung, with two lobes, is smaller and has a cardiac notch to accommodate the heart.
Key Differences
Right lung and left lung are integral components of the respiratory system, enabling oxygen intake and carbon dioxide expulsion. The right lung, consisting of three lobes, has a broader shape and shorter stature due to the liver beneath it. Contrarily, the left lung features two lobes and displays a longer, narrower shape due to the heart's positioning.

In terms of function, both the right lung and the left lung participate in the vital process of respiration, however, their structural differences cater to other anatomical nuances. The right lung's volume is significantly larger, compensating for the smaller left lung, which is designed to make space for the heart within the thoracic cavity.

Examining the position in the body, the right lung is situated on the right side of the thoracic cavity, separated from the left lung by the mediastinum. On the flip side, the left lung, positioned on the left side, has a distinct, concave cardiac notch, accommodating the heart and contributing to its smaller size relative to the right lung.

Considering health implications, conditions may distinctly affect the right lung and left lung due to their varied shapes and sizes. For instance, the right lung is often more susceptible to aspiration pneumonia due to the more vertical orientation of its primary bronchus, in contrast to the left lung.

From an anatomical perspective, the fissures within the right lung and left lung also exhibit distinctions. The right lung features oblique and horizontal fissures, creating its three lobes: superior, middle, and inferior. Conversely, the left lung contains only an oblique fissure, dividing it into just two lobes: superior and inferior.

Right Lung
Possessing three lobes, the right lung accommodates for optimal oxygen transport and CO2 expulsion.
A deep inhale visibly expands the right lung, crucial for adequate oxygenation of blood.

Left Lung
Integral to respiration, the left lung operates in tandem with the right lung, managing airflow.
Ensuring the health of the left lung is pivotal for maintaining balanced respiratory function.

Right Lung
Encased within the ribcage, the right lung’s structural integrity supports effective respiratory action.
Injury to the ribcage can impair the right lung's functionality, compromising respiratory efficacy.

Left Lung
The left lung features a cardiac notch, providing spatial accommodation for the heart.
The cardiac notch gives the left lung a distinctive, slightly curved appearance on radiographic images.

FAQs
Why is the right lung larger than the left lung?
The right lung is larger to compensate for the left lung’s space allocation for the heart.

What is the cardiac notch and which lung is it associated with?
The cardiac notch is a concave space in the left lung that allows room for the heart.
