Anatomy of the Kidney: Blood Vessels and Urine Drainage Pathways, Exercises of Anatomy
A detailed diagrammatic view of the human kidney, focusing on the blood vessels and the pathway of urine drainage. It includes labels for major structures such as the inferior vena cava, renal artery, renal vein, nephron, and various blood vessels. The document also explains the functions of different parts of the kidney, such as the cortex and medulla, and the roles of the proximal and distal convoluted tubules.

Don’t forget to study the loop in both orientations!
It helps if you start at Bowman’s Capsule and work your way through the nephron from there.

Don’t forget to look for these on the corpuscle model…they help you to know when you have hit the PCT.
