Which factor helps in maintaining an increasing osmolality towards the inner medullary interstitium?
 a. Counter current pattern in vasa recta
b. Counter current pattern in Henle’s loop
c.proximity between the Henle’s loop and vase recta

 Shapes of Henle’s loop and vasa recta are

Read the following statements about the excretory system in humans: I. A fall in GFR can activate the JG cells to release renin. II. ADH can also affect the kidney function by its constrictory effects on blood vessels. III. The proximity between the Henle's loop and vasa recta, as well as the counter-current in them help in maintaining an increasing osmolarity towards the outer medullary interstitium. IV Our lungs remove large amounts of CO_(2) (108 litres/day). V. Renal calculi are the stone or insoluble mass of crystallised salts like oxalates within the kidney. How many of these are correct?

The increase in osmolarity from outer to inner medullary interstitium is maintained due to : (i) Close proximity between Henle's loop and vasa recta (ii) Counter current mechanism (iii) Selective secretion of HCO 3¯ and hydrogen ions in PCT (iv) Higher blood pressure in glomerular capillaries

Assertion :- Mammals have the ability to produce a concentrated urine. Reason :- Counter current mechanism occurs in vasa recta and Henle's loop.
