Renal Cortex – 1, 2, 3, 4, 5; Renal Medulla – 6, 7
Reason — In the figure, 1 is the afferent arteriole, 2 the glomerulus, 3 the efferent arteriole, 4 the proximal convoluted tubule and 5 the distal convoluted tubule. All of these lie in the renal cortex. The loop of Henle (6) and the collecting duct (7) run down into the renal medulla.
