WHAT IS EMPHYSEM COPD?

This outcomes from harm to your lungs' air sacs (alveoli) that obliterates the walls inside them and makes them converge into one monster air sac. It can't retain oxygen too, so you get less oxygen in your blood according to Pulmonologist in Delhi. Harmed alveoli can make your lungs loosen up and lose their springiness. Air gets caught in your lungs and you can't inhale it out, so you feel winded.
