Question

Mark the odd one in each of the following series
Afferent arteriole, Henle's loop, vasa recta, efferent arteriole.

Answer 1

Henle's loop is odd one among these.

The glomerulus is a tuft of capillaries formed by the afferent arteriole – a fine branch of the renal artery. Blood from the glomerulus is carried away by an efferent arteriole. The efferent arteriole emerging from the glomerulus forms a fine capillary network around the renal tubule called the peritubular capillaries. A minute vessel of this network runs parallel to the Henle’s loop forming a ‘U’ shaped vasa recta.

While loop of Henle is part of the renal tubule.
