A scoliosis curve can be C- or S-shaped. In severe cases, the spine will rotate and twist, causing the ribs to stick out more on one side. Most cases of scoliosis are mild and cause no health problems. In severe cases, the twisting of the spine and ribs reduces space within the chest cavity. This can interfere with breathing and put strain on the heart. Untreated scoliosis can also compress and damage the spinal nerves, leading to paralysis.
How COPD Affects Breathing. When your lungs are healthy and work properly, the air you breathe moves freely in and out. Inside your lungs are airways, which are called bronchial (BRONK-ee-ol) tubes. The airways branch into clusters of air sacs called alveoli (AL-vee-OL-ee). When you breathe in fresh air, it moves into the air sacs, where oxygen is absorbed into the blood stream and carried to all parts of your body. The air sacs also remove carbon dioxide from the blood. When you breathe out, stale air with carbon dioxide passes out of your airways and lungs.
