3d model that shows the damaged tissue from a covid-19 patient’s lungs
What happens inside a covid-19 patient’s lungs? The lining of the respiratory tree becomes injured, causing inflammation. This in turn irritates the nerves in the lining of the airway. Just a speck of dust can stimulate a cough.
when this gets worse, it goes past just the lining of the airway and goes to the gas exchange units, which are at the end of the air passages.
If they become infected they respond by pouring out inflammatory material into the air sacs that are at the bottom of our lungs.
If the air sacs then become inflamed, this causes an “outpouring of inflammatory material (fluid and inflammatory cells) into the lungs which end up with pneumonia.
Lungs that become filled with inflammatory material are unable to get enough oxygen to the bloodstream, reducing the body’s ability to take on oxygen and get rid of carbon dioxide.
That’s the usual cause of death with severe pneumonia
