Glomerulus in section, organ for filtration and production of urine. the glomerulus is the part of the nephron that serves as a filter. He is represented in yellow on this drawing in Bowman's space (blue rounded area). Glomerulus and Bowman's space constitute the renal corpuscle represented in section. The blood to be filtered (red arrow) arrives through the afferent arteriole and exits through the efferent arteriole (in yellow). In the glomerulus, the blood is filtered and exits (blue arrows) in the Bowman space in the form of urine (light blue dots) to be evacuated by the renal tubule (in orange) towards the chalices, pelvis and the ureter to the bladder, not shown in this drawing.
