Coloured SEM of red blood cell covered in fibrin
False-colour scanning electron micrograph (SEM) showing a human red blood cell (erythrocyte) with a fine covering of fibrin, the protein involved in clot formation. Erythrocytes transport oxygen and carbon dioxide around the body. Their biconcave shape is an adaptation which provides the maximum surface area for the exchange of gases. A high degree of elasticity enables them to pass through narrow capillary vessels. Red blood cells are packed with haemoglobin, a red, iron-containing pigment which has a high oxygen carrying capacity. Magnification: x5000 at 6x4.5 cm size Background at top left shows pores in the filter paper on which this sample was examined

Blood Blood Cell Clotting Erythrocyte Fibrin Red Blood Cell Cells
EDITORS COMMENTS
This print showcases the intricate details of a red blood cell covered in fibrin, captured through a false-colour scanning electron micrograph (SEM). The image reveals the vital role played by these cells in our body's functioning. Red blood cells, or erythrocytes, are responsible for transporting oxygen and carbon dioxide throughout our system. Their unique biconcave shape allows for maximum surface area, facilitating efficient gas exchange. The fine covering of fibrin depicted here highlights its crucial involvement in clot formation. This protein is essential for preventing excessive bleeding and promoting wound healing. The high degree of elasticity possessed by red blood cells enables them to navigate through narrow capillary vessels with ease. Packed within each erythrocyte is haemoglobin, a remarkable iron-containing pigment that gives them their distinctive red coloration. Haemoglobin exhibits an exceptional capacity to carry oxygen efficiently throughout the body. Magnified at 5000 times its actual size and presented on a 6x4.5 cm print, this SEM image offers viewers an up-close look at the early stage of clotting within a human red blood cell. Additionally, the background provides a glimpse into the filter paper used during examination, showcasing tiny pores that add further context to this scientific marvel. This extraordinary photograph from Science Photo Library serves as both an educational tool and artistic masterpiece capturing the beauty and complexity found within our own bodies' microscopic world
