Juxtamedullary nephrons

Vedclass · Answer

(N/A) Juxtamedullary nephrons: These constitute about $15\%$ of the total nephrons. These nephrons are larger in size. Their loops are associated with the $Vasa \ recta$. Blood first passes through the glomerulus and then flows through the $Vasa \ recta$ of the Loop of Henle. In these units,the Loop of Henle is very long and extends deep into the medulla.$(B)$ Cortical nephrons: The Loop of Henle is short and extends only a little into the medulla. They constitute about $85\%$ of the total nephrons. The $Vasa \ recta$ is absent or highly reduced. The efferent arteriole emerging from the glomerulus forms a fine capillary network around the renal tubule,called the $Peritubular \ capillary$ network. $A$ minute vessel from this network runs parallel to the Loop of Henle to form a '$U$' shaped $Vasa \ recta$.
