A significant role in the maintenance of high osmolarity of medullary interstitial fluid. D. Reabsorption of 70-80 percent of electrolytes and water. E. Conditional reabsorption of Na^(+) .

(A) The ascending limb of loop of Henle is impermeable to water (B) The descending limb of loop of Henle is impermeable to water (C) The ascending limb of loop of Henle is permeable to water (D) The descending limb of loop of Henle is permeable to electrolytes,

Which of the following statements about the functioning of the kidney is CORRECT ? I. On a average , 1100-1200 ml of blood is filtered by the kidneys per minute which constitute roughly 1/5th of the blood pumped out by both the Ventricles of the heart in a minute . II. JGA is a special sensitive region formed by cellular modifications in the distal convoluted tubule and glomerulus at the location of their contact . III. The ascending limb of Henle's loop is impermeable to water but allows transport of electrolytes. IV. The collecting duct allows passage of small amounts of urea into the medullary interstitium to keep up the osmolality.

Read the given statements and select the correct options: Statemetn-I: The ascending limb of loop of Henle is impermeable to water. Statemetn-II: Hence the filtrate becomes hypertonic.

Identify the correct statement (s) regarding the human kidney I. It is responsible for the storage of nutrients such as glycogen II. It concentrates the urine by actively transporting water from the filtrate. III. It produces more dilute urine, when the collecting ducts become less permeable to water. IV. The kidney gets rid of urea from the body by secreting it into the descending arm of the loop of Henle. V. It responds to antidiuretic hormone by increasing urine output VI. It reponds to atrial natiutetic factor by decreasing urinary excretion VII. Kidney functions are controlled by negative feedback circuits involving ADH, RAAS and ANF.

The high osmolarity of the renal medulla is maintained by all of the following except (i) Active transport of salt from the upper region of the ascending limb (ii) The spatial arrangement of juxta medullary nephrons (iii) Diffusion of urea from the collecting duct (iv)Diffusion of salt from the ascending limb of the loop of Henle (v) Diffusion of salt from the descending limb of the loop of Henle
