pharynx
This chronic inflammatory airway disease is characterized by wheezing and shortness of breath.
asthma
This simple device measures oxygen saturation of the blood.
pulse oximeter
During inhalation, the diaphragm contracts and moves in this direction to allow the lungs to expand.
downward
These tiny air sacs are the site of gas exchange in the lungs.
alveoli
This suffix means 'inflammation' and is found in terms like 'bronchitis'.
-itis
This disease is an infection of the lung tissue, often caused by bacteria or viruses.
pneumonia
This test measures lung volumes and airflow using a mouthpiece and machine.

oxygen
This muscle is the primary muscle for breathing located below the lungs.
diaphragm
The prefix 'pneumo-' refers to this organ or substance.
