Introduction:
Breathing is a process of movement of air into and out of the lungs in order to regulate the gas exchange with the environment of the body. It mostly brings in the oxygen and flushes out the carbon dioxide.

Which one of the following is a possibility for most
of us in regard to breathing, by making a conscious
effort?
(a) One can breathe out air totally without oxygen.
(b) One can breathe out air through Eustachian
tube by closing both nose and mouth.
(c) One can consciously breathe in and breathe
out by moving the diaphragm alone, without
moving the ribs at all.
(d) The lungs can be made fully empty by forcefully
breathing out all air from them.
(Mains 2011)
Gas exchange in the lungs takes place in the (a) alveoli, (b) bronchioles, (c) segmental bronchi, (d) lobar bronchi.
Cigarette smoke irritates the lining of your airway, causing it to [6]; this makes the diameter of your airway [7] and slows the movement of air. Smoke also slows the movement of [8].
Is a "smoker's cough" due to damage of alveoli or bronchial tubes? [9]
Is a long-term smoker's difficulty breathing due to damage of alveoli or bronchial tubes? [10]
[11] is a lung disease caused by damage to the alveoli.
