Vasa recta is the cluster of blood capillaries present in the nephron of human beings. It isderived from X and surrounds Y, where X are arterioles and Y are tube-like structures.Which of the following CORRECTLY identifies X and Y?
Correct answer: C. C
- A. A
- B. B
- C. C
- D. D
Explanation
The vasa recta is a series of blood capillaries in the nephron that play a crucial role in the counter-current exchange system, essential for concentrating urine. It is derived from the efferent arterioles of the glomerulus and primarily surrounds the loop of Henle. Therefore, option C is correct because it identifies X as efferent arterioles and Y as the loop of Henle. The other options are incorrect because they either incorrectly identify the source of the vasa recta or the structures it surrounds.

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.
