How do we breathe explain?
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

The Lungs. The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product.
How many lungs do we have?
You have two lungs, the left lung and the right lung. The left lung is slightly smaller and has a notch to give room for the heart. Each lung is divided into lobes—the left lung has two and the right lung has three—which are similar to balloons filled with sponge-like tissue.

One large study found that 20 years after quitting smoking, the risk for COPD drops to the same level as if you’d never smoked. And after 30 years, the risk of lung cancer also drops to nonsmoking levels. “The sooner you quit smoking, the more likely the lungs are able to heal,” Englert says.
