Series of illustrations on the structure of the human kidney. The whole organs at left reveal surface anatomy & a section showing blood supply & ureter. At right are the structures of a nephron, the functional unit of excretion in the kidney. Blood circulating in branches of the renal artery (red) is filtered through a knot of capillaries into the surrounding Bowman's capsule (cup-shaped). Water, nitrogenous waste & other substances pass through the renal tubule, where reabsorption into blood may occur. The remaining urine drains into the bladder. ALL MORAL RIGHTS ASSERTED.
