Keeping this in view, what is the main function of the lungs?
The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.
Also Know, can you live without lungs? In general, you need at least one lung to live. This is not a routine procedure and one cannot live long without both lungs. However, it is possible to live with just one lung. Pneumonectomy is the surgical removal of an entire lung, usually performed due to disease such as lung cancer, or injury.
Besides, how do lungs work?
Your lungs bring fresh oxygen into your body. They remove the carbon dioxide and other waste gases that your body's doesn't need. Your diaphragm tightens and flattens, allowing you to suck air into your lungs. To breathe out (exhale), your diaphragm and rib cage muscles relax.
How does air enter the lungs?
They contract to pull your rib cage both upward and outward when you inhale. As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air travels to the alveoli, or air sacs.
