Kidney glomeruli. Coloured scanning electron micrograph (SEM) of glomeruli (red) surrounded by supporting tissue in a kidney. The outer layer of these round structures are podocyte cells that interlock to cover an inner coiled ball of capillaries. The function of the glomeruli is to filter waste products from the blood. After the reabsorption of certain substances elsewhere in the kidney, the liquid is transported to the bladder as urine.
