Illustration of nephron structure in human kidney
Illustration of a nephron, the functional unit of excretion in the human kidney. As a blood filtering system, a nephron is richly supplied with capillaries from branches of the renal artery (red) and vein (blue). At centre right, a knot of capillaries (the glomerulus) is surrounded by Bowmans capsule (blue). It is here that excretory products are filtered from the blood, and pass into a convoluted tubule (yellow). Urine is con- centrated in this tubule, particularly in the thin loop of Henle (at bottom) with useful products re- absorbed into the blood. A collecting duct (left) passes this urine to the ureter, then bladder

EDITORS COMMENTS
This print showcases the intricate structure of a nephron, the fundamental unit responsible for excretion in the human kidney. The illustration vividly depicts how this blood filtering system is abundantly supplied with capillaries stemming from branches of the renal artery (highlighted in red) and vein (distinguished in blue). At the center-right, an entanglement of capillaries known as the glomerulus is enveloped by Bowman's capsule, represented by its distinctive blue hue. This crucial site serves as a gateway where waste products are filtered out from the blood and channeled into a convoluted tubule depicted in yellow. The process continues as urine becomes concentrated within this tubule, particularly within the thin loop of Henle located at its base. Here, valuable substances are reabsorbed back into circulation while excess waste remains to be expelled. A collecting duct on the left side then carries this concentrated urine towards the ureter before reaching its final destination –the bladder. This awe-inspiring artwork not only provides an insight into our complex urinary system but also highlights Science Photo Library's commitment to delivering exceptional visual representations of scientific subjects like anatomy and physiology. Through their meticulous attention to detail and artistic prowess, they have successfully captured both beauty and functionality within this mesmerizing image.
