tbr test 3 bio q 144

[2010premed]

Choose the correct sequence of structures within and around the nephron of the human kidney through which blood and filtrate must pass in order to separate waste products (to be excreted in the urine) from water and solutes (to be reabsorbed by the kidney):
A. Efferent arteriole, glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, peritubular capillaries
B. Renal artery, afferent arteriole, glomerulus, Bowman's capsule, loop of Henle, proximal convoluted tubule, distal convoluted tubule
C. Afferent arteriole, glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct
D. Renal artery, afferent arteriole, glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, peritubular capillaries

Answer: D

why not C?

Answer: D

why not C?

the question stem says we're looking for structures around the nephron as well. Answer C doesn't have structures that surround the kidney nephron. Choices A and B are in the incorrect order
