Question

A minute vessel of the efferent arterioles runs parallel to the Henle’s loop to form

• A. vasa recta
• B. peritubular capillary
• C. malpighian tubules
• D. glomerulus

Answer 1

The correct option is A vasa recta

The glomerulus is a tuft of small blood vessels located within Bowman's capsule. Blood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole.
The efferent arteriole is the connecting vessel between the glomerulus and the peritubular capillaries and vasa recta.
Peritubular blood capillaries surround the renal tubules PCT and DCT of the cortical nephrons. Vasa recta are the blood capillaries that surround the renal tubule called the loop of Henle in the juxtamedullary nephrons. Vasa recta is reduced or absent in cortical nephrons.
