Renal corpuscle, light micrograph (C023/9431) T-Shirt

Light microscopy of two renal corpuscles in the kidney. Entering and exiting the corpuscle at one pole are arterioles which form a compact branched mass of capillary loops with red blood cells inside them. These capillaries, known as a glomerulus, provide for a selective filter of blood plasma that circulates through them, constituting the primary mechanism by which the kidney removes waste products from the blood stream that later results in urine production. This initial filtrate also called provisional urine, passes into the gap (Bowman's space) between the glomerulus and the margin of the corpuscle called Bowman's capsule. There may be a million renal corpuscles in each adult human kidney, all of which are developed before birth ther...
