Counter current multiplier system occurs between ________ and ________.
- ALoop of Henle and Bowman's Capsule
- Correct answerBVasa recta and Loop of Henle
- CCollecting ducts and Loop of Henle
- DVasa recta and glomerulus
Solution
Mammals have the ability to produce concentrated urine, which is facilitated by the counter current mechanism.
The flow of filtrate in the two limbs of Henle's loop is in opposite directions, forming a counter current. Similarly, the flow of blood through the two limbs of the vasa recta is also in a counter current pattern.
The close proximity between the Henle's loop and the vasa recta, along with the counter current in them, helps in maintaining an increasing osmolarity towards the inner medullary interstitium. This mechanism is known as the counter current multiplier system.
Therefore, the counter current multiplier system occurs between the vasa recta and the loop of Henle.
Answer: Vasa recta and Loop of Henle
The flow of filtrate in the two limbs of Henle's loop is in opposite directions, forming a counter current. Similarly, the flow of blood through the two limbs of the vasa recta is also in a counter current pattern.
The close proximity between the Henle's loop and the vasa recta, along with the counter current in them, helps in maintaining an increasing osmolarity towards the inner medullary interstitium. This mechanism is known as the counter current multiplier system.
Therefore, the counter current multiplier system occurs between the vasa recta and the loop of Henle.
Answer: Vasa recta and Loop of Henle
Hence, the correct answer is option: 'B'.
