60
Atelectasis
Failure of lung to expand completely because passages are blocked, also used to describe condition where fetus lung has not fully expanded at birth, can cause partially or totally collapsed lung
61
Atel
Incomplete
62
-ectasis
Stretching
63
Tuberculosis, multidrug-resistant tuberculosis
Infectiupous disease caused by mycobacterium tuberculosis, can infect other parts if body not just lungs, usually occurs when body is weakened by another condition
64
Pneumonia
Smallest bronchioles and alveoli filled with pus and other liquid, bacterial, viral, aspiration, mycoplasma, and pneumocystis carinii are some but not only types of pneumonia
65
Bronchopneumonia, lobar pneumonia/double pneumonia
Bp: affects patches of bronchioles in both lungs, most dangerous to very ill, weak, old or young, lp: affects one or more lobes, dp: lobar pneumonia involving both lungs and bacterial pneumonia
