What is the importance of having a long loop of Henle and short loop of Henle in a nephron?

Text Solution

Verified by Experts

When the animals have long loops of Henle, they produce concentrated urine, whereas the animals like where dehydration is not an issue have only short Henle .s loop produce dilute urine.

    Assertion: In the descending limb of loop of Henle the urine is hypotonic, while in ascending limb of loop of Henle, the urine is hypertonic. Reason: Descending limb is impermeable to water while ascending limb is impermeable to Na^(+)

    A square loop of side 10 cm and resistance 1 Omega is moved towards right with a constant velocity V_0 as shown in . The left arm of the loop is in a uniform magnetic field of 2 T. the field is perpendicular ot the plane of the drawing and is going into it. the loop is connected to a network of resistors each of value 3 Omega with what speed should the loop be moved so that a steady curfrent of 1 mA flows in the loop.

    a. Obtain an expression for the mutual inductance between a long straight wire and a square loop of side a as shown in the figure. b. Now assume that the straight wire carries a current of 50 A and the loop is moved to the right with a constant velocity, v=10m//s . Calculate the induced emf in the loop at the instant when x=0.2m . Take a=0.1m and assume that the loop has a large resistance.
