This medical illustration accurately depicts the anatomy and physiology of the kidney. Labels on the anatomy drawing include kidneys, renal arteries and veins, abdominal aorta, ureters, bladder and urethra. The medical illustration also shows enlargement of the kidney with oxygenated (oxygen-rich) blood flowing in through the arteries through the renal hilum into the renal cortex, while deoxygenated (oxygen-poor) blood flows out. The final two anatomy drawings display an enlarged view of the kidney tissue with an inset of the nephron, the functional unit of the kidney. more
