Alveoli (alveolus)
Air sacs at the smallest subdivision of the bronchial tree; oxygen and carbon dioxide are exchanged through the alveolar walls and the capillaries that surround them
Bronchi (Bronchus)
One of two branches from the trachea that conducts air into the lungs, where it divides and subdivides. The branchings resemble a tree; therefore, they are referred to as a bronchial tree
Larynx
Location of vocal cords; air enters from the pharynx (voice box)
Lungs
Two spongelike organs in the thoracic cavity. The right lung has 3 lobes and the left lung has 2 lobes
Nose
Lined with mucous membranes and fine hairs; acts as a filter to moisten and warm air
Pharynx
Serves as food and air passageway; air enters from the nasal cavities and/or mouth and passes through the pharynx to the larynx. Food enters the pharynx from the mouth and passes into the esophagus
Sinuses
Air cavities within the cranial bones; membrane lining the air cavities produces mucus, which drains into the nasal passages (paranasal sinuses)
Thorax
Chest; the part of the body between the neck and the diaphragm encased by the ribs. The thoracic cavity is the hollow space between the neck and diaphragm
Trachea
Passageway from air to the bronchi from the larynx (windpipe)
