Answer to Question 1

ANS: A, B
The urine formed by the nephrons flows from the distal tubules and collecting ducts through the duct of Bellini and the renal papillae into the calyces.

Answer to Question 2

ANS: D
The vasa recta is a network of capillaries that forms loops and closely follows the loops of Henle and is the only blood supply to the medulla. This need is not met by the renal arteries, the arcuate arteries, or the peritubular capillaries.
