Lung and lymph nodes labelled – image description

The illustration shows the position of the lungs in the chest. It shows the windpipe, also called the trachea, coming down from the neck. The trachea divides into two tubes called the right bronchus and left bronchus. The right bronchus goes into the right lung and the left bronchus into the left lung.

There are two layers around the outside of each lung. The layer closest to each lung is labelled the inner pleura. The second layer is labelled the outer pleura. There is a very small space between the two layers of the pleura. This is the pleural cavity.

The illustration shows groups of pea-sized lymph nodes connected to each other by fine tubes. The lymph nodes are close to the trachea and to the right and left bronchi. There are also lymph nodes on each side of the neck extending along the collar bones.
