(A) | Activation of JG cells and release of renin |
(B) | Angiotensin II activated release of aldosterone |
(C) | Fall in glomerular blood pressure |
(D) | Reabsorption of Na+ and water from distal convoluted tubule |
(E) | Angiotensinogen is converted to Angiotensin I and then to Angiotensin II |
1. | (C), (A), (E), (B), (D) | 2. | (A), (D), (E), (C), (B) |
3. | (A), (D), (C), (B), (E) | 4. | (B), (A), (E), (D), (C) |
Which one of the following hormones reduces blood pressure?
1. Antidiuretic hormone
2. Atrial Natriuretic factor
3. Aldosterone
4. Angiotensin-II
(a) | Angiotensin II activates the cortex of adrenal gland to release aldosterone. |
(b) | Aldosterone leads to increase in blood pressure. |
(c) | ANF acts as a check on renin-angiotensin mechanism. |
(d) | ADH causes vasodilation. |
(e) | Vasopressin is released from adenohypophysis. |
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 |
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. |
A decrease in blood pressure/volume will not cause the release of?
1. Atrial natriuretic factor
2. Aldosterone
3. ADH
4. Renin
Which of the following does not favour the formation of large quantities of dilute urine?
Which of the following causes an increase in sodium reabsorption in distal convoluted tubule?
1. Increase in aldosterone levels
2. Increase in antidiuretic hormone levels
3. Decrease in aldosterone levels
4. Decrease in antidiuretic hormone levels
A fall in glomerular filtration rate (GFR) activates:
1. Adrenal cortex to release aldosterone
2. Adrenal medulla to release adrenaline
3. Posterior pituitary to release vasopressin
4. Juxta glomerular cells, to release renin
1. | Exposure to cold temperature stimulates ADH release |
2. | An increase in glomerular blood flow stimulates the formation of angiotensin II |
3. | During summer when the body loses a lot of water by evaporation, the release of ADH is suppressed |
4. | When someone drinks a lot of water, ADH release is suppressed. |
