What are the vasa recta?
A) Capillary extensions of the afferent arterioles
B) Capillary extensions of the efferent arterioles
C) Regions of the renal tubule
D) Vessels that supply blood to the glomerulus
E) Vessels that supply blood to the proximal convoluted tubule
Vasa Recta
A series of straight capillaries in the kidney that serve as a counter-current exchange mechanism, concentrating urine and conserving water.
Efferent Arterioles
Small blood vessels that are part of the kidney's microcirculation, carrying blood away from the glomeruli toward the vasa recta.
Afferent Arterioles
Afferent arterioles are small blood vessels that carry blood towards the glomeruli of the kidney, playing a key role in the regulation of blood pressure and filtration rate.

Final Answer :
B
Explanation :
The vasa recta are capillary networks that extend from the efferent arterioles of the juxtaglomerular apparatus in the kidney, playing a crucial role in the process of urine concentration and the reabsorption of water.
