SEM of lung alveoli
Lung alveoli. Coloured Scanning Electron Micro- graph (SEM) of lung tissue, showing alveoli and a pulmonary blood vessel. At centre is the lumen of a large blood vessel (yellow) lined with elongated endothelial cells. To its right is an elongated blue arteriole; at upper left is a blue bronchio- lus with dark lumen. The other tissue (blue, pink) comprises alveoli air sacs with their interstital walls lined with capillaries. Bronchioli pass air into the alveoli where the gases of carbon dioxide and oxygen are exchanged during respiration. These gases pass directly out of, and into, the blood- stream. Magnification: x900 at 6x7cm size. Magnification: x1, 150 at 4x5 inch size

EDITORS COMMENTS
This print from Science Photo Library offers a mesmerizing glimpse into the intricate world of lung alveoli. The colored Scanning Electron Micrograph (SEM) showcases the delicate network of lung tissue, with its remarkable alveoli and a pulmonary blood vessel stealing the spotlight. At the center of attention lies a large blood vessel's lumen, painted in vibrant yellow and lined with elongated endothelial cells. To its right, an elongated blue arteriole adds to the visual symphony, while at the upper left corner, a blue bronchiole with a dark lumen makes its presence known. Surrounding this central spectacle is an array of tissues in shades of blue and pink, representing alveoli air sacs adorned with their interstitial walls lined by capillaries. The bronchioli play their vital role by ushering air into these enchanting alveoli where respiration takes place. It is within these tiny sacs that carbon dioxide and oxygen engage in their life-sustaining exchange before seamlessly passing into and out of our bloodstream. With magnifications reaching x900 at 6x7cm size or x1,150 at 4x5 inch size, this image allows us to appreciate the extraordinary complexity hidden within our lungs' anatomy. A true testament to nature's brilliance and human physiology's wonders captured through SEM technology by Science Photo Library – an invaluable resource for those seeking knowledge about healthy lungs and respiratory systems.
