Light micrograph of a section of normal human kidney tissue, showing 6 glomeruli & a blood vessel running horizontally across the image. The glomerulus & Bowman's capsule comprise the renal corpuscle, which together with the renal tubule, constitute the nephron, the functional unit of the kidney. A glomerulus consists of a knot of tightly packed capillaries surrounded by a Bowman's Capsule. The Bowman's space, into which the glomerular filtrate is passed, appears as a white space surrounding each Bowman's capsule. The glomeruli filter blood entering the kidney of fluids such as excess water & of other impurities. Magnification: X 120 at 35mm size.
