Respiratory tract, artwork
Respiratory tract. Computer artwork showing the various stages and structures of the human respiratory tract. Air is drawn in through the oral and/or nasal cavities, and passes down the trachea, into the bronchi and then through the bronchioles into the alveoli. Once in the alveoli, the oxygen in the air dissolves in the damp lining of the alveolar sacs and diffuses through their walls into the blood system. On exhaling, carbon dioxide passes out of the blood into the alveoli and is expelled in the opposite direction

EDITORS COMMENTS
This artwork from Science Photo Library beautifully captures the intricate structures and stages of the human respiratory tract. The image showcases the complexity of our breathing system, highlighting its vital role in supplying oxygen to our bodies. In this computer-generated illustration, we can observe how air enters through either the oral or nasal cavities before making its way down the trachea. From there, it travels into the bronchi and further into smaller bronchioles until reaching the alveoli. These tiny sacs are where gas exchange takes place - as oxygen dissolves in their moist lining, it diffuses through their walls and enters our bloodstream. The process is not one-sided; when exhaling, carbon dioxide exits our blood vessels and is expelled back into the alveoli to be eliminated from our bodies. This continuous cycle ensures that we receive a constant supply of fresh oxygen while removing waste gases. The detailed labeling within this artwork allows us to appreciate each component involved in respiration: from organs like lungs and diaphragm to specific anatomical features such as larynx, esophagus, and oral cavity. It serves as a reminder of just how intricately designed our bodies are for optimal functioning. Science Photo Library's print provides an educational tool that both informs and fascinates viewers about this essential biological process within us all.
