Question 7 The major determinant of passive water absorption in the collecting ducts is: achve bult co rimay acitve 1. Water availability in the proximal tubule. au-passive Sodium concentration in the collecting ducts. 3. Aquaporins. Vasopressin.. 5. None of the above. x Question 8 Which of the following statements regarding kidney processes is incorrect? 1. Excretion rate is equal to the filtration rate if no reabsorption or secretion occurs. 2. Excretion rate is higher than the filtration rate if the filtrate is partly reabsorbed 3. Excretion rate is zero if all filtrate is reabsorbed. 4. Excretion rate is higher than filtration rate when filtrate is not absorbed but secretion occurs. 5. All of the above are incorrect. Question 9 Which of the following statements regarding the glomerular filtration rate is incorrect? 1. It is determined by the sum of hydrostatic and colloid osmotic forces across the membrane. 2. GFR = Kr/ Net filtration pressure. 3. Hydrostatic pressure inside the glomerular capillaries promotes filtration. 4. Hydrostatic pressure in the Bowman's capsule opposes filtration. 5. All of the above are incorrect.Explanation / Answer
ANSWER 7
5. None of these
Because the major determinant of passive water absorption in collecting ducts is ADH the Antidiuretic hormone.
ANSWER 8
2. Excretion rate is higher than the filtration rate if the filtrate is partly reabsorbed is an incorrect statement about kidney process.
ANSWER 9
1. It is determined by sum of hydrostatic and colloid osmotic forces across the membrane.
Because it is the sum of pressure in the glomerular capillaries which favors filtration, osmotic pressure due to the blood proteins and the hydrostatic pressure in Bowman's space which opposes the rate. The net glomerular filtration pressure is the sum of all these 3 forces.
