Lung and lymph nodes labelled – image description

The illustration shows the lungs in the chest with the windpipe, also called the trachea, coming down from the neck. The trachea divides into two tubes called the bronchi going into each lung. The illustration shows groups of pea-sized lymph nodes connected to each other by fine tubes. There are lymph nodes close to the trachea and in the middle of the chest near the right and left bronchi. There are also lymph nodes on each side of the neck going along the bones that connect with each shoulder called the collarbones and also extending down to the underarm area.
