Artwork of kidney nephron with blood vessels
Nephron. Illustration of a nephron from the human kidney, surrounded by blood vessels. Nephrons are where waste products and excess water are removed from the bloodstream in the kidney. Arterial blood (red vessels) enters a tight knot of capillaries (upper centre) called a glomerulus, where fluids pass out of the blood into a hollow tubule (yell- ow). Blood vessels around a loop in the tubule (bottom) recover essential nutrients, salts & some water, and the filtered blood returns to the body in veins (blue). The remaining fluid drains to the bladder as urine. About 140 litres of fluid passes into the kidney tubules each day in a normal adult. Of this, 99% is reabsored

EDITORS COMMENTS
This print showcases the intricate artwork of a kidney nephron with blood vessels. The illustration depicts a nephron, which is responsible for removing waste products and excess water from the bloodstream in the human kidney. Surrounding this vital component are an intricate network of blood vessels. The image highlights the journey of arterial blood as it enters a tightly woven cluster of capillaries known as a glomerulus, located at the upper center. Within this glomerulus, fluids pass out of the blood and into a hollow tubule depicted in yellow. As the process continues, other blood vessels can be seen surrounding a loop in the tubule at its bottom section. These vessels play an essential role in recovering necessary nutrients, salts, and some water before returning filtered blood to the body through blue veins. Ultimately, any remaining fluid drains into the bladder as urine. It is fascinating to note that on average, approximately 140 liters of fluid enter these kidney tubules each day in healthy adults; however, an astonishing 99% is reabsorbed during filtration. This remarkable artwork not only provides insight into our anatomy but also serves as a reminder of how intricately designed our bodies are to perform crucial functions like waste removal and maintaining fluid balance within us.
