Ascending limb of Henle’s loop is ____________to water whereas the descending limb is___________to it.

Assertion : In the descending limb of loop of Henle , the urine is hypertonic , while in ascending limb of loop of Henle , the urine is Hypotonic . Reason : Descending limb is impermeable to Na' while ascending limb is impermeable to H_(2)O

Statement-1 : In the descending limb of loop of Henle, the urine is hypertonic, which in ascending limb of loop of Henle, the urine is hypotonic. Statement-2 : Descending limb is impermeable to sodium, while ascending limb is impermeable to water.

Henle’s loop plays an important role in concentrating the urine.

The nephron is a hollow, convoluted tube of cells. It is engineered to concentrate urine by removing water at which of the following sites? I. Proximal convoluted tubule II. Descending limb of the loop of Henle III. Ascending limb of the loop of Henle

Two narrow bores of diameters 3.00mm and 6.0mm are joined together to form a U-tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube? Surface tension of water at the temperature of the experiment is 7.3 times 10^-2 N m^-1 .Take the angle of contact to be zero and density to water to be 1.0 times 10^3 kg m^-3
