Q. No.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
(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
For the ejection of urine the voluntary signal is given by
(1) ANS
(2) CNS
(3) PNS
(4) Afferent arterioles
Atrial Natriuretic Factor (ANF) is released by
(1) Atria of heart
(2) Ventricles of heart
(3) Right atrium only
(4) Left atrium only
ANF causes
(1) Decrease of blood pressure
(2) Vasodilation
(3) Increasing the diameter of vessels
(4) All of these
From where does the signal for Micturition arise?
(1) By stretching of the urinary bladder
(2) By relaxing of urniary bladder
(3) By reduction in the size of urinary bladder
(4) By contraction of urinary bladder
The release of urine does not take place by
(1) Contraction of smooth muscles of the bladder
(2) Simultaneous relaxation of urethral sphincter
(3) Relaxation of smooth muscels of the bladder
(4) Both B and C
