Our varied collection of illustrations of the respiratory system includes images of the lungs, lung cancer, bronchioles, diseases of the lungs and images of the pediatric respiratory system. Many of our illustrations are labelled, making them ideal for use as teaching or presentation material.

The respiratory system is a collection of body parts and organs that are responsible for taking in oxygen and expelling carbon dioxide. Air is inhaled through the trachea and travels into the lungs via bronchial tubes. The alveoli in the lungs are responsible for transporting oxygen into the blood and expelling carbon dioxide.
Both the left lung and right lung consist of lobes. The right lung has three lobes and the left lung has two lobes and is smaller than the right, as the heart is positioned at the top of the left lung. The inside surface of the lungs consists of tiny air sacs called alveoli. Inside the alveoli, oxygen enters the blood via capillaries and carbon dioxide is released from the capillaries and is exhaled when breathing out.
Diseases of the Lungs and Respiratory System
Our illustrations include diseases of the lungs and respiratory systems such as bronchiolitis, lung cancer and tumours, as well as techniques used in diagnosing and treating lung conditions such as biopsy, thoracoscopy and bronchoscopy.
Common lung conditions include chronic obstructive pulmonary disease (COPD), pneumonia, lung cancer and asthma. Some diseases do not have a clear cause, but high levels of air pollution or allergens in the environment, smoking and genetic factors can also be risk-factors in developing diseases of the respiratory system. Many conditions, such as asthma and COPD, can only be treated and not completely cured.
