A 3D model reveals the ravaged tissue within a COVID-19 patient's lungs. What happens inside these lungs when they're ravaged by the virus? The lining of the respiratory tree becomes severely damaged, triggering inflammation that irritates the nerves in the airway's lining. Even a small speck of dust can set off a cough. As this condition worsens, it moves past the airway's lining and reaches the gas exchange units at the end of the air passages. If these units become infected, they respond by releasing inflammatory material into the air sacs at the bottom of our lungs. When the air sacs become inflamed, an outpouring of fluid and inflammatory cells occurs, resulting in pneumonia. Lungs filled with inflammatory material are unable to obtain sufficient oxygen for the bloodstream, impairing the body's ability to absorb oxygen and eliminate carbon dioxide. This is typically the cause of death in severe cases of pneumonia.
