If Henle's loop were absent from mammalian nephron, which of the following is to be expected:
- There will be no urine formation
- There will be hardly any change in the quality and quantity of urine formed
- The urine will be more concentrated
- The urine will be more dilute
The Correct Option is D
Solution and Explanation
If Henle's loop (loop of Henle) were absent from a mammalian nephron, it would have a significant impact on urine formation. Henle's loop plays a crucial role in the concentration of urine by creating an osmotic gradient in the renal medulla, which allows for the reabsorption of water from the collecting duct. Without Henle's loop, the urine would be more dilute because the nephron would not be able to concentrate it effectively.
So, the correct answer is (D): The urine will be more dilute.

Mechanism Human Excretory System
Excretory System Organs
Kidneys- Kidneys are bean-shaped structures located on either side of the backbone. In human each adult kidney size is 10-12 cm with a width of 5-7 cm and weighs around 120-170g and it have an inner concave structure.
Ureter - A pair of thin muscular tubes called the ureter. Ureter comes out of each kidney extending from the renal pelvis and it carries urine from the kidney to the urinary bladder.
Urinary Bladder - muscular sac-like structure which stores urine. The urinary bladder is emptied by the process of micturition.
Urethra- This tube comes out from the urinary bladder and helps to expel urine out of the body. It acts as the common route for sperms and urine in males.
