Red blood cells, SEM
Red blood cells. Coloured scanning electron micrograph (SEM) of red blood cells (erythrocytes). Red blood cells are biconcave, disc-shaped cells that transport oxygen from the lungs to body cells. They circulate around the body in the blood and also remove carbon dioxide to the lungs for exhalation. Their red colour comes from the oxygen-carrying protein haemoglobin. Red blood cells are the most abundant cell in the blood. They have no nucleus and are about 7 micrometres in diameter

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate beauty of red blood cells. Magnified under a scanning electron microscope, these biconcave, disc-shaped cells play a crucial role in our body's circulatory system. Responsible for transporting oxygen from the lungs to every cell in our body, they ensure our survival and well-being. The multiple red blood cells captured in this image highlight their abundance within the bloodstream. Lacking a nucleus and measuring about 7 micrometers in diameter, these remarkable cells are perfectly designed for their function. Their vibrant red color is derived from the presence of haemoglobin, an oxygen-carrying protein that gives them their characteristic hue. As they travel through our veins and arteries, they also remove carbon dioxide waste products and transport them back to the lungs for exhalation. This false-colored SEM photograph not only provides us with a glimpse into the microscopic world but also serves as a reminder of the complexity and elegance found within our own bodies. It is a testament to human biology at its finest – showcasing both form and function harmoniously intertwined. Whether you're fascinated by anatomy or simply appreciate scientific marvels, this stunning print will undoubtedly captivate your imagination while reminding you of the incredible mechanisms that keep us alive and thriving.
