What is the main function of the left lung?
They return carbon dioxide through the thin walls to the alveoli. The oxygen-rich blood from your lungs is sent back to your heart, where it’s pumped to your entire body. The carbon dioxide is breathed out of the lungs and alveoli through your mouth and nose.

The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
Are lungs located in front or back?
The lungs are found in the chest on the right and left side. At the front they extend from just above the collarbone (clavicle) at the top of the chest to about the sixth rib down. At the back of the chest the lungs finish around the tenth rib.
Can your lungs hurt in your back?
Pleurisy is inflammation of the pleura, which are two thin membranes that line and protect the chest and lung cavities. This inflammation can make breathing difficult and cause a sharp pain that can spread to the shoulders and back. Other symptoms of pleurisy can include shortness of breath, coughing, and a fever.
Can lung pain be felt in the back?
Lung cancer. Chest and back pain can also occur as a symptom of lung cancer. Although chest pain is a common symptom, the Dana-Farber Cancer Institute reports that 25 percent of people with lung cancer reported back pain as a symptom.
Why do my lungs hurt in my back?
An injury to the lining of the lung, inflammation due to an infection or invasion by cancer can all cause pain in the chest. In the case of lung cancer, back or chest pain is caused by the tumor(s) irritating the nerve endings in the pleura, as well as in the bone or muscles that the tumor is invading.
What are the symptoms of inflamed lungs?

- Feeling tired after physical activity.
- A general sense of fatigue.
