Voice box (larynx)
The upper respiratory tract includes the following:
The lower respiratory tract includes the following:
Voice box (larynx)
Airways (bronchi and bronchioles)
Air sacs (alveoli)
What is the function of the lungs?
The lungs take in oxygen. The body’s cells need oxygen to live and carry out their normal functions. They also get rid of carbon dioxide, a waste product of the cells.
The lungs are a pair of cone-shaped organs made up of spongy, pinkish-gray tissue. They take up most of the space in the chest, or the thorax (the part of the body between the base of the neck and diaphragm). The lungs are enveloped in a membrane called the pleura and separated from each other by the mediastinum: This area contains the following:
Heart and its large vessels
The right lung has 3 lobes. The left lung has 2 lobes. When you breathe, the air:
Enters the body through the nose or the mouth.
Travels down the throat through the larynx (voice box) and trachea (windpipe).
Goes into the lungs through tubes called main-stem bronchi:
One main-stem bronchus leads to the right lung and one to the left lung
In the lungs, the main-stem bronchi divide into smaller bronchi
Then into even smaller tubes called bronchioles
Bronchioles end in tiny air sacs called alveoli
