The air that we breathe in penetrates the actual trachea, from where it is carried to the lungs through the two main branches of the trachea (bronchial tubes).
The exchange of carbon dioxide and oxygen occurs in alveoli, which are microscopic sacs that are present in the lungs. Medically referred to as pneumonia, a lung infection takes place when pathogens such as bacteria, trojans, or fungi go into the lungs and multiply.
