Correct answer: D. Vasa recta
- A. Netted capillaries
- B. Afferent capillaries

- D. Vasa recta
Explanation
The network of capillaries parallel to the loop of henle is called vasa recta. Peritubular capillaries are the blood capillaries that surround the PCT and DCT of the cortical nephrons. Afferent capillaries supply the blood to be filtered to glomerulus. The correct answer is therefore, D.

About Kidney and Urinary System
The kidney and urinary system remove nitrogenous wastes, regulate water and ion balance, and help maintain blood pH through filtration, selective reabsorption and secretion. Questions cover nephron structure, ultrafiltration, the loop of Henle, collecting ducts, urine formation and the roles of ADH and aldosterone, while distinguishing excretion from egestion.
