Lung alveoli, SEM
Lung alveoli. Coloured scanning electron micrograph (SEM) of alveoli (air spaces) in the lungs. Blood vessels containing erythrocytes (red blood cells) are also seen. Alveoli are the smallest divisions of the airways in the lungs, and are the sites of gaseous exchange. Here, oxygen is taken up by the blood from inhaled air, and carbon dioxide is released to be exhaled. Magnification: x40 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of lung alveoli, captured through a scanning electron microscope (SEM). The image reveals a colorful array of air spaces within the lungs, known as alveoli. These microscopic structures are crucial for gaseous exchange in the respiratory system. The vibrant false colors highlight the delicate network of capillaries that surround each alveolus. These blood vessels carry erythrocytes, or red blood cells, which play a vital role in transporting oxygen and removing carbon dioxide from our bodies. With a magnification of x40 when printed at 10 centimeters wide, this photograph offers an up-close glimpse into the physiological wonders occurring within our lungs. It serves as a reminder of how intricately designed our bodies are to facilitate respiration and sustain life. Beyond its scientific significance, this image is also visually striking. The contrasting hues and patterns create an artistic composition that blurs the line between biology and aesthetics. It invites viewers to appreciate both the complexity and elegance found within our own anatomy. Whether you're fascinated by biology or simply captivated by stunning imagery, this mesmerizing print from Science Photo Library will undoubtedly spark curiosity about the remarkable processes happening inside us every day.
