Q. No.Kidneys is efficiently monitored and regulated by hormonal feedback mechanisms which does not involve
A. Hypothalamus
B. JGA
C. Heart
D. Liver
A. Hypothalamus
B. JGA
C. Heart
D. Liver
Osmoreceptors in the body are not activated by
(1) Changes in blood volume
(2) Body Fluid volume
(3) Body Fluid ionic concentration
(4) Temperature of the body
Hypothalamus is stimulated by osmoreceptors and make the neurohypophysis to release
(1) ADH
(2) Vasopressin
(3) Both A or B
(4) Oxytocin
ADH facilitates water reabsoption and
1. Prevent diuresis
2. Promote diuresis
3. Cause diuresis
4. Both 1 and 2
ADH cannot cause
(1) Blood pressure increase
(2) Glomerular Blood Flow increase
(3) Increase in GFR
(4) Loosening of Glomerular capillary
The JG cells are activated by
(1) A fall in Glomerular blood flow
(2) A fall in Glomerular blood pressure
(3) A fall in GFR
(4) All of these
JG cells release…….. which converts…..in…....to angiotensin I.
1. Renin, Angiotensinogen, Heart
2. Rennin, Angiotensinogen, Heart
3. Renin, Angiotensinogen, Blood
4. Renin, Angiotensin II, Blood
Which of the following is a powerful vasoconstrictor?
(1) Angiotensinogen
(2) Angiotensin I
(3) Angiotensin II
(4) Rennin
Angiotensin II has effects over
(1) Adrenal medulla
(2) Adrenal cortex
(3) Blood vessels
(4) Both B and C
