Did you know that we have 300 million aveoli in our lungs? that is equivalent to 70 square feet which measures out to be the size of a tennis court! so cool. atelectasis is a severe condition in which the aveoli collapse due to pulmonary edema, bronchiole obstruction, increased mucous secretions, immobility and other factors. this helps me remember so i figured i would share!
