(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

(3) Increasing the diameter of vessels
(4) All of these
Which of the following mechanisms is antigonistic to RAAS pathway?
(1) ANF mechanism
(2) Counter-current pathway
(3) Both A and B
(4) Micturition
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
