Lymph node, SEM
Lymph node. Coloured scanning electron micrograph (SEM) of a freeze fracture section through a lymph node, showing part of the medullary sinus. Lymph nodes are rounded bodies found throughout the lymphatic system, mostly in the neck, groin and armpit areas. They act as filters, preventing foreign objects entering the bloodstream. The Reticular cells (dark red) make up a connective tissue mesh. White blood cells (lymphocytes, pink), red blood cells (red) and macrophages (light brown) are also seen. Magnification: x800 at 6x7cm size

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate beauty of a lymph node. The image, captured using a scanning electron microscope (SEM), reveals a freeze fracture section through the lymph node, specifically highlighting part of the medullary sinus. Lymph nodes are essential components of our lymphatic system and can be found throughout our bodies, particularly in areas like the neck, groin, and armpits. Acting as powerful filters, they play a crucial role in preventing foreign substances from entering our bloodstream. In this mesmerizing SEM image, we can observe various elements that make up the lymph node's structure. The dark red reticular cells form an intricate connective tissue mesh that supports and organizes other cellular components within the node. Additionally, pink-colored lymphocytes (white blood cells) alongside red blood cells and light brown macrophages are visible. With its magnification set at x800 on a 6x7cm size scale, this photograph offers us an extraordinary glimpse into the microscopic world hidden within our own bodies. It serves as a reminder of both the complexity and elegance present in human anatomy while emphasizing how vital these structures are for maintaining our immune system's functionality.
