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. Emphysema: A form of COPD usually caused by smoking. 2  The fragile walls between the lungs' air sacs (alveoli) are damaged, trapping air in the lungs and making breathing difficult. 3  Chronic bronchitis: Repeated, frequent episodes of productive cough, usually caused by smoking.
Mammalian lungs are located in the thoracic cavity where they are surrounded and protected by the rib cage, intercostal muscles, and bound by the chest wall. The bottom of the lungs is contained by the diaphragm, a skeletal muscle that facilitates breathing.Breathing requires the coordination of the lungs, the chest wall, and most importantly, the diaphragm.o increase the volume of the lungs, the chest wall expands. This results from the contraction of the intercostal muscles, the muscles that are connected to the rib cage. Lung volume expands because the diaphragm contracts and the intercostals muscles contract, thus expanding the thoracic cavity.
