Free and printable high-quality diagrams of lungs are available for you to help your respiratory system study! The lungs are part of the lower respiratory tract that begins at the trachea and branches into the bronchi and bronchioles, and which receive air breathed in via the conducting zone. Check out the lung diagram below to see the detailed parts of the lung anatomy.
The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. At the bottom of the trachea, or windpipe, there are two large tubes. These tubes are called the main stem bronchi, and one head left into the left lung, while the other heads right into the right lung. At the end of each bronchiole is a special area that leads into clumps of teeny tiny air sacs called alveoli. More printable diagrams of lungs are available below.
There are very small blood vessels called capillaries. These capillaries are so tiny that the cells in your blood need to line up the single file just to march through them. Try to label the following parts: alveoli, trachea, bronchi, bronchioles, diaphragm, lung, mouth, and nasal passage on the unlabeled lung diagram.
