Red blood cells, SEM
Red blood cells, coloured scanning electron micrograph (SEM). Red blood cells (erythrocytes) are biconcave, giving them a large surface area for gas exchange, and highly elastic, enabling them to pass through narrow capillary vessels. They have no nucleus, but their interior is packed with haemoglobin. Haemoglobin is a red iron-containing pigment that enables these cells to carry oxygen to body tissues and to transport waste carbon dioxide back to the lungs. Magnification: x2650 when printed 10 centimetres tall

EDITORS COMMENTS
This print showcases the intricate beauty of red blood cells, as captured through a scanning electron microscope (SEM). The image reveals multiple red blood cells, or erythrocytes, which play a vital role in our body's functioning. Their unique biconcave shape provides them with a large surface area for efficient gas exchange. Additionally, their remarkable elasticity enables them to navigate through narrow capillary vessels. What makes these cells even more fascinating is their lack of nucleus. Instead, their interior is densely packed with haemoglobin – a crimson iron-containing pigment that gives them their characteristic color. Haemoglobin serves a crucial purpose by facilitating the transport of oxygen from the lungs to various tissues throughout the body and carrying waste carbon dioxide back to be exhaled. With an impressive magnification level of x2650 when printed at just 10 centimeters tall, this SEM image allows us to appreciate the intricate details and complexity within each red blood cell. It offers us a glimpse into the microscopic world that sustains our existence. This mesmerizing print not only highlights the beauty found within biology but also serves as a reminder of how intricately designed our bodies are on both macroscopic and microscopic levels.
