Bladder lining, SEM
Bladder lining. Coloured scanning electron micrograph (SEM) of the internal surface folds of a bladder in its contracted state. The bladder is the organ that receives and stores urine from the kidneys. The walls of the bladder (a hollow organ) have to expand and contract to cope with varying volumes of urine. Urine is a waste product that is produced by the kidneys. The kidneys filter the blood to remove metabolic waste such as urea. The resulting urine drains from the kidneys through the ureters into the bladder. The urine is then removed from the body by urination through the urethra. Magnification unknown

EDITORS COMMENTS
This print showcases the intricate beauty of a bladder lining in its contracted state. Through the lens of a scanning electron microscope (SEM), we are granted an up-close view of the internal surface folds that allow this organ to fulfill its vital role in our urinary system. The bladder, a hollow organ, serves as a reservoir for urine received from the kidneys. Its walls possess remarkable elasticity, enabling them to expand and contract as needed to accommodate varying volumes of urine. This dynamic process is essential for maintaining proper urinary function within our bodies. Urine itself is a waste product produced by our hardworking kidneys, which filter metabolic waste like urea from our bloodstreams. Once filtered, the resulting urine travels through slender tubes called ureters and collects within the bladder until it is ready for elimination. In this mesmerizing image, we witness nature's design at work. The colored SEM reveals an array of folded structures composing the healthy bladder lining. These folds not only contribute to its flexibility but also increase surface area for efficient absorption and secretion processes. As we marvel at this microscopic wonder captured by Science Photo Library, let us appreciate how seamlessly our body's systems collaborate to maintain balance and eliminate waste effectively – reminding us once again of nature's extraordinary complexity and elegance.
