Human lungs
Human lungs. Anatomical artwork of the human lungs and respiratory system. The heart (which has been removed here) is located between the lungs. At top is the cartilage (blue) of the voicebox and trachea (windpipe), leading down to the lungs. The trachea splits into the bronchi that supply air to each lung. At left, the cutaway section shows the airways (bronchioles) that get smaller and smaller as they branch off from the bronchi. They eventually end in alveoli (yellow), air sacs where gaseous exchange of oxygen and carbon dioxide with the blood occurs. This oxygenated blood is then passed to the heart and pumped around the body

EDITORS COMMENTS
This print showcases the intricate beauty and complexity of the human lungs and respiratory system. The artwork, created with meticulous detail, highlights the various components that make up this vital organ. In the center of the image, we see a pair of healthy human lungs, with the heart absent as it usually resides between them. Above them lies the striking blue cartilage of the voicebox and trachea, also known as the windpipe. This crucial pathway leads down to supply air to each lung through bronchi, which branch out from the trachea. The cutaway section on the left provides a fascinating glimpse into our internal anatomy. It reveals an elaborate network of airways called bronchioles that progressively decrease in size as they extend from larger bronchi. These delicate structures ultimately terminate in alveoli – small yellow sacs responsible for exchanging oxygen and carbon dioxide with our bloodstream. As oxygenated blood is received by these remarkable alveoli, it is then transported back to our heart for distribution throughout our body via blood vessels. This process ensures proper oxygenation and sustains life itself. This awe-inspiring illustration not only serves as a testament to human physiology but also reminds us of how intricately interconnected all systems within our bodies truly are.
