The lungs are a pair of spongy, air-filled organs located on either side of the chest. Our lungs are tasked with the vital job of providing oxygen that the body needs and removing the carbon dioxide that is toxic to the body. While our lungs work normally, we are rarely aware of our breathing but when our lungs are forced to work harder to supply oxygen and eliminate the carbon dioxide, we feel shortness of breath. This requires the body to spend extra energy on breathing and may cause constant fatigue, which diminishes one's quality of life. If the lungs get damaged beyond a point when even extra oxygen and other therapies fail, a lung transplant becomes the final treatment option to experience a normal lifestyle.
