This mechanism of breathing also helps to allow you to talk.
The left lobe is also smaller as it has to make room for the heart.
Each lung has three surfaces, named after their location in the thorax.

They are the mediastinal surface, diaphragmatic surface, and costal surface.
Inside the lungs are bronchitubes that run from thetracheainto each lung.
There are approximately 30,000 bronchioles in each lung and 600 million alveoli in each lung combined.
The lungs also consist ofpulmonary arteries,pulmonary veins, bronchial arteries, as well aslymph nodes.
Deoxygenated blood is sent from the right ventricle of the heart to the lungs via the pulmonary artery.
Location
The lungs are guarded by the rib cage, and they are located right above thediaphragm.
Each lung is located near different organs in the body.
Together with your heart, the lungs take up almost the entire width of the rib cage.
Anatomical Variations
Its common to see anatomical variations when it comes to the lungs.
According to research published inAnatomy & Cell Biology,the most common include genetic and environmental factors during development.
Function
The lungs are responsible for bringing in fresh air into the body.
From there, air travels to the blood vessels surrounding the alveoli.
The red blood cells release carbon dioxide and exchange it for oxygen, which binds to hemoglobin molecules.
The oxygenated blood circulates through the body.
Carbon dioxide and other gases the body doesnt need are exhaled out by the lungs.
The act of the lungs exhaling is also what helps you speak.
