False-colour SEM of a section of lung tissue
Lung tissue. False-colour scanning electron micrograph (SEM) of a section of lung tissue. The image shows several alveolar ducts and alveolar sacs (large, irregular dark areas) together with a few alveoli (smaller round dark areas). The alveoli are separated by a porous membrane known as the interalveolar septum. The tiny openings in the interalveolar septum are sectioned capillaries and it is in this intricate network of capillaries that the exchange between carbon dioxide and oxygen takes place. Many red blood cells are scattered throughout the frame. Magnification: x110 at 6x7cm size. x170 at 4x5ins

EDITORS COMMENTS
This print showcases a false-colour scanning electron micrograph (SEM) of a section of lung tissue. The intricate details captured in this image provide an extraordinary glimpse into the inner workings of our respiratory system. The dark, irregular areas represent alveolar sacs and ducts, while smaller round dark areas depict individual alveoli. These vital structures are separated by the interalveolar septum, a porous membrane that plays a crucial role in gas exchange. Within the interalveolar septum, we can observe tiny openings which are actually sectioned capillaries. It is through this intricate network of capillaries that the exchange between carbon dioxide and oxygen occurs. This process is essential for sustaining life as red blood cells transport oxygen to every corner of our body. With a magnification level of x110 at 6x7cm size or x170 at 4x5ins, this SEM image offers an up-close view that would otherwise be impossible to witness with the naked eye alone. This stunning photograph not only highlights the beauty found within our own anatomy but also serves as a reminder of how complex and remarkable our bodies truly are.
