The nephron loops and the collecting ducts are surrounded by the
A)vasa recta.
B)efferent glomerular arterioles.
C)peritubular capillaries.
D)segmental arteries.

Question

Quizplus · Accepted Answer

The vasa recta are specialized capillaries that follow the loop of Henle and the collecting ducts in the nephron, providing oxygen and nutrients to these structures.

Answer: B 
 The efferent glomerular arterioles transport blood away from the glomerulus and lead to the peritubular capillaries, which surround the entire nephron (including the loop of Henle and collecting ducts) in the renal cortex.

Answer: C 
 The peritubular capillaries are located in the renal cortex and surround the entire nephron (including the loop of Henle and collecting ducts), providing nutrients and removing waste products from the tissue.

Answer: D 
 Segmental arteries are the main arteries that branch off the renal artery and supply the kidney with blood, but they do not directly surround the loop of Henle or collecting ducts.

The Nephron Loops and the Collecting Ducts Are Surrounded by the
