Artwork of trachea and bronchi of the human lungs


Rights Managed


Lung anatomy. Illustration of the trachea and bronchiole network of the human lungs. At top is the larynx (voicebox) through which air enters the trachea (windpipe, upper centre). The trachea branches into two bronchi which enter the pair of lungs (not seen). Both the trachea and the bronchi are strengthened with rings of cartilage (blue). At right a cutaway section of the trachea is shown. Within the lungs the bronchi divide into an internal network of smaller and finer bronchioles (pink). These bronchiole tubes end in tiny air sacs called alveoli (not seen). In the alveoli gases are exchanged: inhaled oxygen enters the blood and carbon dioxide is breathed out.
