False-colour SEM of a group of red blood cells
Red blood cells (erythrocytes). False-colour scanning electron micrograph of a group of red blood cells on the endocardium, the innermost layer lining the heart. During its short life (about four months) a red blood cell covers about 15km every day for a total of 1500km. In a litre of blood there are normally 5000 billion red blood cells. They transport oxygen from the lungs to the tissues where it is necessary for all metabolic processes. The endocardium is composed of a thin layer of flattened epithelial cells supported by an underlying basement membrane of connective tissue. Magnification: x2220 at 6x7cm size. x3750 at 4x5

EDITORS COMMENTS
This print showcases the intricate world of red blood cells, offering a mesmerizing glimpse into their vital role within our bodies. Captured using a false-colour scanning electron microscope, this image reveals a group of red blood cells residing on the endocardium, the innermost layer lining the heart. Did you know that during its short lifespan of approximately four months, each red blood cell travels an astonishing 15 kilometers every day? This means that over its lifetime, it covers an impressive distance of 1500 kilometers! It is truly remarkable to contemplate the tireless journey these tiny cells embark upon daily. Contained within just one liter of blood are an astounding 5000 billion red blood cells. Their primary function is to transport oxygen from our lungs to all tissues in our body where it is crucial for various metabolic processes. Without them, life as we know it would not be possible. The endocardium showcased in this image consists of a delicate layer composed of flattened epithelial cells supported by connective tissue forming an underlying basement membrane. The magnification used for this photograph allows us to appreciate these minute details at x2220 when printed at 6x7cm size and even more impressively at x3750 when printed at 4x5 dimensions. This stunning visual representation serves as a reminder of the incredible complexity and beauty found within our own bodies – a testament to both nature's ingenuity and scientific advancement.
