Collecting Duct

Which of the following statements is false regarding the collecting duct? I. Collecting duct is a straight duct II. It extends from the cortex to medulla III. Large amount of water could be reabsorbed from it to produce concentrated urine IV. Small amount of urea diffuses out from it into the medulla to keep up the osmolarity V. It plays a role to maintain pH and ionic balance of blood by the selective secretion of H^(+)andK^(+) ions

Arrange the following structures in the order that a drop of water entering the nephron would encounter them. Afferent arteriole Bowman's capsule Collecting duct Distal tubule Glomerulus Loop of Henle Proximal tubule Renal pelvis

Arrange the following structures in the order that a drop of water entering the nephron would encounter them. (a) Afferent arteriole (b) Bowman's capsule (c) Collecting duct (d) Distal tubule (e) Glomerulus (f) Loop of Henle (g) Proximal tubule (h) Renal pelvis

Prepare a flow chart of filtrate flow in the nephrone using the following terms. Collecting duct PCT, DCT, Ascending limb of Henle's loop, descending limb of Henle's loop. Bowman's capsule. Counter current system plays an important role in concentrating urine Name any two regions inside the kidney, where the counter current system is seen.

In the following questions , a statement of assertion (A) is followed by a statement of reason (R). A: ADH response is observed during increased osmolarity due to dehydration. R : Vasopressin promotes water uptake from collecting ducts and DCT.

Statement-1: The final reabsorption of water from the urine into the blood occurs through the collecting duct of a mammalian nephron resulting in thhe production of hyperosmotic urine. Statement-2: The loop of henle creates a sodium gradient in the interstitial fluid.
