Red blood cells, SEM C015 / 8790
Red blood cells. Coloured scanning electron micrograph (SEM) of human red blood cells (erythrocytes). Red blood cells are biconcave, giving them a large surface area for gas exchange, and highly elastic, enabling them to pass through narrow capillary vessels. The nucleus and other organelles are lost as the cells mature. The cells interior is packed with haemoglobin, a red iron-containing pigment that has an oxygen-carrying capacity. The main function of red blood cells is to distribute oxygen to body tissues and to carry waste carbon dioxide back to the lungs

EDITORS COMMENTS
This print showcases the intricate beauty of human red blood cells, as captured by a scanning electron microscope. The image reveals the distinct biconcave shape of these cells, which provides them with a large surface area for efficient gas exchange. Their remarkable elasticity allows them to navigate through narrow capillary vessels effortlessly. As red blood cells mature, they lose their nucleus and other organelles, making space for an abundance of haemoglobin within their interior. Haemoglobin is a vital pigment that carries oxygen throughout the body. Its iron-containing structure gives it the ability to bind and transport oxygen molecules effectively. The primary role of these crimson-hued warriors is to distribute life-sustaining oxygen to all tissues in our body while simultaneously collecting waste carbon dioxide and transporting it back to the lungs for elimination. This crucial function makes red blood cells indispensable components of our circulatory system. In this visually stunning photograph, SUSUMU NISHINAGA from Science Photo Library has masterfully captured the essence of these microscopic marvels. It serves as a reminder of the intricate biological processes that occur within us every moment, highlighting both their elegance and significance in maintaining our overall health and vitality.
