D

a and c

Text Solution

Verified by Experts

The correct Answer is:
B
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 inner medullary interstitium, i.e. from `300 mOsmolL^(-1)` in the cortex to about `1200 mOsmolL^(-1)` in the innerÂ

 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.

Assertion: The two limbs of Henle ’s loop fonns a counter current Reason: The flow of blood in the two limbs of Henle’s loop is in opposite direction.

counter current mechanism between loop of Henle and Vasa recta result in reabsorption of water from

Assertion: The Henle's loop and vasa recta play a significant role in producing a concentrated urine. Reason: The counter current arrangement of Henle's loop and vasa recta helps in this.

Counter current machanism helps in concentrating urine in animals and mainly operaters on {:(a.,"Henle's loop",b.,"Vasa-react"),(c.,"PCT",d.,"DCT"):}
