Which of the following answers is CORRECT?The larger representation of urea receptors in the kidney is placed in the proximal convoluted tubuleCollecting Tubule cells are less metabolically active than Distal Tubule cellsChloride is highly responsible for the function of the sodium potassium ATPase pumpThe percentage of reabsorption of chloride in the proximal convoluted tubule is the same as the bicarbonate reabsorptionThe sodium chloride cotransporter is placed in the thick segment of the ascending limb of Loop of Henle

Which is not true for the function of renal tubules in the following ?DCT-conditional reabsorption of Na+ and water, selective secretion of hydrogen ,potassium ions and NH3Collecting duct- maintaince of pH  and ionic balances of blood by selective secretion of H+ and K+PCT-100% electrolytes and water are reabsorbed, also helps to maintain the pH and ionic balance of blood.Loop of Henle-reabsorption is minimum in ascending limb.

Regarding sodium reabsorption, which one of the following statements in INCORRECT?Group of answer choicesAlways occurs in the descending limb of the loop of Henle.It plays a role in the reabsorption of glucose and amino acids in the proximal tubule.It is under hormonal control in the distal tubule and collecting duct.In the loop of Henle sodium reabsorption contributes to the formation of a concentrated urine.

Au niveau du tubule rénal :AL'hyperkaliémie inhibe l'élimination urinaire du K+ sous l'effet de l'aldostéroneBLa diminution du PH diminue la sécrétion du K+ dans le TCDCLors de la surcharge hydrique l'élimination de l'urée est réduiteDUne réabsorption accrue de l'urée dans le TCDE2/3 du K+ filtré sera réabsorbé par un cotransport Na+K+/2C1- dans le TCP

Which of the following occurs to allow the kidneys to form concentrated urine?*1 pointA lot of NaCI is secreted at the ascending limb.A lot of NaCI is reabsorbed at the descending limb.A lot of water is reabsorbed at the descending limb.A lot of water is reabsorbed at the proximal convoluted tubule.

Choose the false statement from the following:-Reasorption from ascending limb of loop of henle is maximumMammals have ability to produce a concentrated urineOsmotic gradient in Kidneys is maintained by NaCl and ureaANF mechanism, acts as a check on the renin-angiotensin mechanism
