Light micrograph of a section of the kidney from a newborn child. It shows the cortex of the kidney studded with round renal corpuscles. A renal corpusle consists of a Bowman's capsule within which is the glomerulus, a network of capillaries involved in the first stage of blood filtration in the kidney. The tissue around the renal corpuscles consists of renal tubules, into which the filtrate from the Bowman's capsules drains. Selective reabsorption of material occurs here and the urinary filtrate passes to the renal pelvis and then the ureters. Magnification: x20 at 35mm size.
