The lungs provide oxygen for energy production in the body, and are part of the respiratory system. Air enters through the mouth and is absorbed into alveoli, which have a large surface area. The diaphragm controls breathing, and the lungs also filter blood and protect the heart. The lungs supply our body with the oxygen […]
Emphysema is a chronic respiratory disease that damages lung tissue, making breathing difficult and preventing oxygen from entering the bloodstream.

There are several main effects of […]
