Peritubular Capillary Network — NEET Biology
📚 Practice ConceptA loop of capillary running parallel to the Henle's loop.
Assertion (A): Both Henle’s loop and vasa recta contribute to the counter-current mechanism. Reason (R): The flow of filtrate in Henle’s loop is counter-current while the flow of blood in vasa recta follows a parallel pattern.
View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
NCERT states “The flow of filtrate in the two limbs of Henle’s loop is in opposite directions and thus forms a counter current. The flow of blood through the two limbs of vasa recta is also in a counter current pattern.” The Assertion is true - both contribute to counter-current mechanism. The Reason is false - both have counter-current flow, not parallel flow in vasa recta.
