The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.

Pneumonia: Infection in one or both lungs. 2  Bacteria, especially Streptococcus pneumoniae, are the most common cause. 3  Asthma: The lungs' airways (bronchi) become inflamed and can spasm, causing shortness of breath and wheezing. 4  Allergies, viral infections, or air pollution often trigger asthma symptoms.
