Q. No.Presence of which of the following conditions in urine is indicative of Diabetes Mellitus:
1. Uremia and Renal Calculi
2. Ketonuria and Glycosuria
3. Renal Calculi and Hyperglycaemia
4. Uremia and Ketonuria
Which of the following would help in prevention of diuresis?
| 1. | Reabsorption of Na+ and water from renal tubules due to aldosterone |
| 2. | Atrial natriuretic factor causes vasoconstriction |
| 3. | Decrease in the secretion of renin by JG cells |
| 4. | More water reabsorption due to under secretion of ADH |
The increase in osmolarity from outer to inner medullary interstitium is maintained due to :
(i) Close proximity between Henle's loop and vasa recta
(ii) Counter current mechanism
(iii) Selective secretion of HCO3¯ and hydrogen ions in PCT
(iv) Higher blood pressure in glomerular capillaries
(1) Only(ii)
(2) (iii) and (iv)
(3) (i), (ii) and (iii)
(4) (i) and (ii)
Select the correct statement :
(1) Atrial Natriuretic Factor increases the blood pressure.
(2) Angiotensin II is a powerful vasodilator.
(3) Counter current pattern of blood flow is not observed in vasa recta.
(4) Reduction in Glomerular Filtration Rate activates JG cells to release renin.
Identify the correct statement:
