Your lungs have been examined using ultrasound.

An ultrasound examination involves sending ultrasound waves from an ultrasound probe in the body. Depending on the structure of the tissue, different numbers of ultrasound waves are reflected. These waves are then converted to images that can be viewed on a screen.

To use ultrasound to closely examine tissue or organs, the ultrasound probe should be as close as possible to the location being examined. For this purpose, the ultrasound probe can be inserted into the body using a tube.

The ultrasound probe was pushed down through your windpipe to the lower airways. When we breathe, the air gets into the body via the respiratory tract. The respiratory tract can be divided into the upper and the lower respiratory tracts. The nose and throat form part of the upper respiratory tract. The lower respiratory tract begins at the larynx. This includes the trachea and the bronchia.
