The lungs are a pair of organs located in the chest cavity that are responsible for facilitating the process of breathing. They are spongy and elastic, and their main function is to take in oxygen from the air we breathe and transfer it to the bloodstream, while also removing carbon dioxide from the body.
The lungs are made up of millions of tiny air sacs called alveoli, which are surrounded by a network of blood vessels called capillaries. When we inhale, air travels through the nose or mouth, down the trachea, and into the lungs, where it fills the alveoli. Oxygen from the air then diffuses across the walls of the alveoli and into the bloodstream, while carbon dioxide from the blood diffuses into the alveoli and is then exhaled during the process of breathing out.
