Assertion A: The renal fluid becomes increasingly concentrated when it flows down in the descending limb of loop of Henle towards the inner medulla but its concentration decreases in the ascending limb when it flows towards the cortex Reason R: The descending limb of the loop of Henle reabsorbs water, the ascending limb is impermeable to water but salts are reabsorbed

Read the following statements and select the correct option Statement 1 : When the urine moves through the descending limb, it becomes hypertonic to blood plasma and as it passes through the ascending limb of Henl's loop it becomes hypotonic to blood plasma Statement 2 : The decending limb is permeable to sodium ions, while the ascending limb is impermeable to sodium ions

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

Characteristic of metanephric kidney is (a) Hypotonic urine (b) Uric acid formation (c) Loop of Henle (d) Hormone production

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

Read the following statement and choose the correct option I. Asceding limb of Henle's loop is permeable to water II. Tubular cells secrete substance like H^(+), K^(+) and ammonia into filtrate III. There is maximum reabsorption in Henle's loop IV. Conditional reabsorption of Na^(+) occurs in DCT V. PCT helps in maintaining ionic balance of body fluids

Indicate whether the following statements are true or fals: (a) Micturition is carried out by a reflex. (b) ADH helps in water elimination, making the urine hypotonic. (c) protein free fluid is filtered from blood plasma into the Bowman's capsule, (d) henle's loop plays an important rule in concentrating the urine. (e) Glucose is actively reabsorbed in the capsule. proximal convoluted tubule.
