Kidney filtration, SEM
Kidney filtration. Coloured scanning electron micrograph (SEM) of tissue from a healthy kidney, showing the glomerular structure. The surface of a glomerulus is encased in podocyte cells (purple). These have branching processes that interlock. Below the surface, blood flows through the coiled capillary that is the core of a glomerulus. The function of the glomeruli is to filter waste products from the blood. Liquid passes from the blood through the narrow slits formed by the podocyte cells. After the reabsorption of certain substances elsewhere in the kidney, the liquid is transported to the bladder as urine. Magnification unknown

EDITORS COMMENTS
This print showcases the intricate process of kidney filtration, as seen through a coloured scanning electron micrograph (SEM). The image captures the glomerular structure within a healthy kidney, revealing its vital role in waste product removal. At first glance, we are drawn to the surface of the glomerulus, encased in mesmerizing purple podocyte cells. These cells exhibit branching processes that interlock with one another, forming an elaborate network. Beneath this visually striking surface lies a coiled capillary - the core of the glomerulus - where blood flows continuously. The purpose of these glomeruli is to filter waste products from our bloodstream. Liquid passes through narrow slits created by the podocyte cells and undergoes further reabsorption elsewhere in the kidney before being transported as urine to our bladder. The magnification used for this image remains unknown; however, it allows us to appreciate and marvel at nature's microscopic wonders. This SEM photograph not only provides insight into human anatomy but also highlights biology's complexity and beauty on a cellular level. Science Photo Library has once again captured an extraordinary moment within our own bodies – reminding us of both their fragility and resilience while showcasing scientific advancements in histology and microscopy techniques.
