How does smoking affect the lungs?
Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs. Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis. Cigarette smoking causes most cases of lung cancer.
Does smoking increase or decrease respiratory rate?
Because smoking inflames the airways, it makes it harder for the individual to inhale normal amount of oxygen, thus their respiration rate increases in response to the inflammation to compensate for the decrease in oxygen inhalation.
How does smoking cause respiratory infections?
Cigarette smoke combustion products reportedly increase morbidity and mortality in acute respiratory infections by impairing physical defenses in the respiratory tract, and by impairing cellular and humoral immune responses to microbes (Donowitz and Mandell 1995).
How does smoking cause shortness of breath?
Pathogenetic mechanisms of dyspnea in smokers with COPD.
Exposure to cigarette smoke is the major factor in the pathogenesis of COPD. Risks conferred by smoking interact with genetic susceptibility and respiratory infections to produce expiratory flow limitation (EFL) by loss of elastic recoil and airway inflammation.

Why do smokers have lower lung capacity?
Total Lung Capacity
And at a microscopic level, when fewer alveoli are present (due to destruction by cigarette smoke), or air can’t reach the alveoli (due to cigarette-related damage to the airways and build up of mucus), the intake of breath is also affected. These forces all work together to decrease lung capacity.

Does smoking affect spirometry?
This result suggests that cigarette smoking affects the lung capacity of youth smokers, making the volume that is associated with the FVC test smaller than that of non-smokers. The reduction in FVC of smoker may be explained by the reduction in strength of the respiratory muscles.

Can lungs heal after 40 years of smoking?
The mutations that lead to lung cancer had been considered to be permanent, and to persist even after quitting. But the surprise findings, published in Nature, show the few cells that escape damage can repair the lungs. The effect has been seen even in patients who had smoked a pack a day for 40 years before giving up.
