False-colour SEM showing two renal glomeruli

False-colour scanning electron micrograph of a section of kidney cortex, showing two glomeruli (red & green). A glomerulus is a tiny knot of blood capillaries which lies cupped within a Bowman's capsule (seen here as a U-shaped cavity) and forms part of a kidney nephron. Blood plasma filters through the walls of the glomerulus into the Bowman's capsule and drains into a convoluted tube known as a renal tubule. Here, useful subtances are reabsorbed into the blood, while the remaining waste fluid passes into a collecting duct, enroute to the bladder. The blue region of the image shows renal tubules in various planes of section. Mag: x220 at 6x7cm, x110 at 35mm size
